Hi Martin, I watched the whole video and thought it might drop few words here for you. Funny thing is that I'm a Computer Engineer myself who have no clue whatsoever on basic electronics (even though I studied all of this back in college). Watching this video reminds me of all the useless teachers at the university who are there just because they have a brilliant curriculum; yet they lack of the very basic teaching skills (i.e. clear and concise language, use of analogies for visualization, etc.). I'm very happy I came across your channel, you're very talented and your videos highly instructive. Keep it up and all the best!!
Hi Martin, I liked your video but please explain RMS. I read it up and believe that an updated video explaining the concept of RMS will elevate the value of an already good video. 👍
Thanks a million. I learned a lot. If I had a teacher like you at school/college/uni, I would've never skipped a single lesson. Knowing something is one thing, but explaining/teaching it to others, requires a different kind of talent and set of skills. You have them all. 🙏🙏🙏
As a plumbing heating engineer thats using test equipment every other day i find it very interesting how you explain the different procedures. Excellent video and no other like it on RUclips.Fascinating.
I knew absolutely nothing about multimeters before watching your video, but after watching this I'm learning a great deal. This is an excellent introduction not only about multimeters but a basic understanding of electricity as well. Thank you sir for making this video and sharing with the rest of us.
Thank you so much! This was just what I needed right now as I'm beginning an electrical wire-man education and really struggling with the text book learning. I love your pace, your voice, & especially your careful attention to detail & safety. I'm not a "moron", but I have a learning style that requires visuals, kinetics, and repetition. Thanks again, and God bless you for the thoughtful teaching.
Your video is still helping all kinds of people 8+ years later - Huge thanks for your selfless contribution of valuable time and information! Cheers!!🍻
Having watched your video about multimeter, I told myself "this is exactly the tutorial I need". I will visit your channel to learn more electronic knowledge from you. Thank you very much.
I rarely comment on the videos I watch on RUclips, but I am completely new to electronics and I really loved your tutorial. Thanks a lot for this video and this series. I really appreciate the work you've done.
Tutorial delivered EXACTLY what it's title promised - clearly delivered, stuck to the basics, never got sidetracked into his clearly much deeper tech expertise. Well done. Now this beginner finally understands what he's been doing blindly with his multimeter for years. It's a good thing to go to sleep a little wiser than I woke up. And proud to see a fellow South African sharing his skills freely. Ubuntu.
I have learned more in your 30 minute tutorial than in the six months I have been on the job. Thank you for keeping it simple and willing to share! Oh, AC is more dangerous
As a real novice that cannot "see" electricity, your instructional lessons/explanations are awesome. Please continue the vids. Any explanations on diagnosing, trouble shooting or mere understanding of how appliances, rotating equipment, house hold or recreational vehicle systems would be greatly appreciated.
I have just received a multimeter (Christmas 2020) and needed some direction in using it for the first time excellent basic no frills explanation for beginners .Thanks for part 1 I will be watching this a few times over before moving on (I'm a slow learner) to part 2 and beyond.
You don't just know your work, you have the fundamentals of being great teacher, it's not just about what someone knows but how that person is able to impart knowledge in such manner that it makes learning easy and a pleasure. Thank you very much.
This was an excellent instructional video. I've always had a hard time trying to work with electricity. I'm a visual learner so dealing with or trying to understand electricity always seemed to elude me. Your instructions and explanations along with some really good analogies made this a really good learning experience. I'll look for the second video when I'm comfortable with what you taught me today. Thanks again, nice job. I appreciate your time and effort.
I am not adding nothing that it was not been said before, but I saw several tutorials on youtube to learn how to use a multimeter, and after watching all your videos of how to use a multimeter, I think they are the best on youtube. I not only learn the basics but also learn a lot about electricity that I did know nothing about. So very thanks for that. Terrific work. Keep going. I already subscribe your channel and have been watching a lot of your videos (leaving thumbs up one all of them to thank you) :)
Some people just need to say they know more than you but they haven't shown me more than you. I am sixty nine years and have never learned more than you have taught me. Thank you sir for posting this video that I have learned so much from.
Very nice pesentation. I learned a lot. Thank you so much for your time and presentation. Looking forwared to # 2. Have a Multimeter sitting on the shelf for years but did not know how to use it. Good to have someone like yourself that takes your time to help others. THANKS !
+Wendy S Hey everyone, the greatest results that ive ever had was with the Gregs Electro Blog (i found it on google) without a doubt the most helpful course i've followed.
DC voltage can be a wide range of voltages. 12VDC is one voltage that you commonly see but it can go as high as several thousand volts. You can be killed be DC voltage.
i really appreciate your calm manner. This is a topic that can produce anxiety when the instructor is hyped. You really cover everything well. I have learned much watching. I want more! THANKS
Your video tutorials are so awesome. So easy to digest, especially for a new egg like me! I've subscribed & will learn more about my multimeter. Thank you!
He is right, you are an excellent teacher! You've answered a lot of my questions without me asking! I just bought this multimeter because I really wanted to know how these things worked. Your video's are just unbelievable!! I really do THANK YOU!
Thanks for this very carefully worded, layman-friendly, well thought-out demonstration + explanation. I have known how to measure my motorcycle battery for years (i.e. what holes to plug what wires in, what setting on the meter, what value to expect), but I didn't know what I was doing. Many people have tried to explain it, also using the water hose analogy, but I never grasped it. Much clearer now. Thanks!
Recently my friend came to help me install some LED tail lights onto my wife's motorcycle. He's a whiz with this stuff and I was actually kind of embarrassed when he realized I had no clue how to use a multimeter. I found this video and not only am learning about "how" to use it, but "what it is i'm measuring". This is the basic high school course in electronics that I never had. Subscribed, and will watch each and every one of your informative videos.
I now learning how to use a multimeter and have watched quite a few videos, but so far your tutorial has been the best explained and easiest to follow. Thank you for your hard work. Shout out from Barbados.
I also would like to add that after watching your electricity basics video and I'm only 5 minutes in on this one, I have never understood the symbols on a multimeter such as dc and ac but after seeing the straight line on the oscilloscope and putting two and two together I understand them, no more cringing and hoping I don't have it on the wrong setting now, you are very informative sir
Well explained ,,,thank you very much,,,spent with you an excellent time and very very fruitful,,,keep up educating the nulles like me ,,,salute to you Sir ji
Thank you for the time you've invested in making this very educational video. It's more important for me to learn what to do right, though I admit there will always be room for error no matter how careful one can be. I'm heading on to your next video. I appreciate concise very well articulated explanations. All the best.
Hi I'm a 58 year old female big on DIY projects and constantly has had to resort to getting instructions each and every time I've had a task requiring the uses of a multimeter, somehow you've been able to create a 'break through' for me! Suddenly I understand, it's like you've given me eyesight, I can see now how to get the info I'm needing from multimeter! I bet I've read and watched 100 different lessons on it's uses but none til now have sunk in. SINCERELY THANK YOU 9/14/24
Just come across this video after buying a hyelec ms8233d as building a boeing cockpit and needed guidance on the led set ups. just want to say thank you, very well explained and very easy to follow, baei lekker manir. dankie baei!
Just in cause anyone is wondering: there is a small mistake in the video. The AA battery reading is 1.191, not the 1.91 that's read out. The former is reasonable for a somewhat discharged battery, the latter is much more than a single 1.5V battery would deliver. Considering the video is intended for those with less experience, people might get confused, so I thought it's worth pointing out.
My best friend is a master electrician. I worked with him at a young age and he kept me safe. I am interested how to use my multi meter. And prove to him that I am willing to learn about his work. Hopefully he will appreciate my effort of wanting to learn from him and, I can teach him 100 things that I have mastered. "Jack of all trades, Master of nothing has become, Jack of Mastering much, leaves a bunch Mastering Lunch". Just because you have mastered one thing at one time, does not mean much when you can master many things in a lifetime. Thank you for your awesome tutorials. I and we, will be safe for you.
Very good Video Thanks for your honest easy to understand explanation, as a Moroccan english isnt my first language but I did pick up 90% of it again its the way you use to explain. Thanks
Great video, was clear and easy to understand, looking forward to watching the rest of this series to get a better understanding of how to safely use my multimeter.
Hi from Cape Town Martin! Thanks so much for creating the content that you do. I have been a Software Engineer for about 15 years, and am only now starting to venture into the hardware / electronics side of things. I have watched a number of your videos on my journey of learning electronics, and they are always clear, concise and very informative. I especially like that you put an important emphasis on safety. Way too many cowboys our there making things look quick and easy. I much prefer getting a thorough understanding, including of all risks involved, before diving into an activity. Anyway, just wanted to give you a quick work of thanks for the work that you do, it is helping me and other beginners across the world a great deal :-) Cheers
I am in the U.S., the way you use water compared to electricity is great!!.. I am doing online training to be an RV technician.. very helpful.. will be watching the rest!! Thanks again for the information!
I really do like how you simplify & demonstrate your breaking it down for the common clown like me. L.O.L I wish all others would do the same for making it understandable for the common Joe & talk in laymen terms & bring it down to earth. The problems w/others is they want to sound sophisticated & complicate it. I call this prestige or job insecurity for they have an issue w/an inability to relate w/others.
For anybody wondering about the question: DC is almost always more dangerous to workers, not because it's inherently more powerful, but because of the difference in physiological effects between AC and DC. The nice sine wave of AC current, indicating that the current reverses periodically, means that when you become a current path, your muscles will contract when the current nears either maxima, and relax as it approaches 0. That means that whatever you were doing that caused you to become the current path, you can stop doing (drop the wire/tool). With DC, your muscles just contract and that's it. You have to just hope that your life doesn't depend on being able to release something, because that ain't happening. I haven't watched the next video yet but I'd bet that's more or less what is said.
50Hz in Australia, pretty sure 60Hz in America. AC alternating from +180 degree / -180 degree of the sine wave at 50/60 times PER SECOND....... AC is always more dangerous. Taking holding on to the conductor out of the equation, it is the pulsing that completely fucks up the human body. A very simple google search can confirm this, the number of people saying DC is more dangerous is worrying and i hope you aren't all in the electrical trade.
@Nick Cranston In the 20th century, they taught in schools that DC was way more dangerous. What they taught took several weeks to explain, which makes it hard to accept a 3 second contrary explanation.
I wouldn't be surprised if this guy taught at tech; school, i would class myself as not knowing anything about electricity, however after watching 1 video i now understand voltage a lot more clearly----THANKS HEAPS
I am a beginner to Voltage Meters and I thought this was very informative. Also thoroughly explained. I liked the video and instructional aspect a lot.
hi Martin, You tutorials are fantastic. I am studying HVAC and the guy in the college lectures is by a long way very confusing. (Im British living in Chicago (Accent is killing me)) I can understand you joyfully .. I think you are saving my skin with your tutorials... Thanks you're a star
Excellent. Thank you for the effort you put into this. The actual explanation of the various aspects of electricity makes the biggest different for newbies.
All of you engineering experts giving the uploader flak for being "too informative" need to realize that all the info is there to cover everything. You might have the advantage of a good father figure in your life to teach you these things, or a good school system, but not me. I didn't know shit but thanks to this video I do. It doesn't take an expert to learn this, just as it doesn't take a complete moron to look for this video.
Very true, my father didn't taught me anything, he only put fear and doubt in me for ever wanting to learn things, so videos like that are so awesome to close the gap
Well said! I definitely learned a lot. The basics really do help since I am a novice and just looking to start a new project during this quarantine. Gotta learn something new to keep myself busy! Thanks for the video!
@@mustang19ms I hear you buddy, today i try to teach my kids to be the complete opposite, it's the fear of failing that holding us back, but if you want to learn and grow you have to try and many times fall on you'r ass till you get it right, i'm telling them if you didn't fail at least 5 times a day don't talk to me :)
Ikr? I just did a rant at my 20 year-old about how can they not be teaching this stuff in school.. It's more useful than how to bake a cake, yet they still teach that,lol. I have a similar rant I roll out now and then about why they don't teach stock market investing in high school. We need to equip kids for real life imo.
Thanks so much for your video, I've been left in a weird middle ground. Previous jobs have given me experience but no understanding (think colour by numbers, SOPs and step by steps) I'm now working a better job but I looked a right melon using a multimeter. My favourite line was "lift the that tray with your fingertips, there's a big transformer on the other side"
I am taking CompTIA A+ and it was time to use a volt meter. I have not used one since I was a kid and my dad tried to show me. This video exceeds my expectations for a beginner learning to use a voltmeter!
This video was AWESOME!!!! THANK YOU!!!! MY answer to your question is DC, because it is DIRECT current, meaning the current is straight through, vs. AC which is alternating current and is like an on/off switch or a high/low switch...? I guess II'll see on the next video! :-)
Very helpful tutorial, thankyou. Just starting in this new field, planing to buy my 1st Meter, wached your video on fluke 107. Got first two project today. 1. Measuring DC voltage. 2. Measuring AC voltage.
Great Multi-meter for beginners guide....had to install a light didn't want to kill myself, bought a multi-meter and looked for a guide and found you. My multi meter looks nothing like yours aka cheap, your in-depth guide was perfect. Even though my Multi-meter was set up different you explained the differences between them very well and I was able to test a live wall jack without getting crispy (always a +) in the process. Light was installed I survived to make this comment and can check batteries to boot which came in handy this morning. Good work.
Thank you for this excellent tutorial ! On another note, what would happen if I measure a DC voltage with my multimeter in AC mode and visa versa? Would I run any risk? Hope you can answer, thanks !
thanks so much! amazing explanation. I am a mechanical engineer, so appreciated the pressure/volume flow analogies! Spent quite a few years living in SA - great country.
Dear Lovely brother Mjlorton, Thank you for the above. Now I know a little more about how to use my multimeter sitting on the shelf! I am asking God to be with you all the time and protect you from bad things with your family members. Mr. Philo EBEED from Sudan kHARTOYM.
mjlorton Martin ;Good afternoon , Thanks a lot >............ this video was really helpful!... Very educational and well explained. I always benfit, from you instructions > Maho A > a civil aircraft Engineer and FAA, A&P / IA Inspector . NDT/ NDI level II Inspector . .
Highly instructive methodology. Your introduction was quite clear, starting from a very simple idea of water flowing from a horse pipe connected to a tap, so brilliant. The pace of explanation,step by step and use of simple language vocabulary makes it much much easier for beginners like me who are interested in electricity. I need to watch more and more video tutorials on your channel. Keep it up my "Super Instructor".
Even though it's great information I think an entry level meter would be the three plugged one mate. I personally think you should have done your demo for beginners on one of them
Excellent video. I have not gotten full use of my meter and your videos are showing me other ways I can use for testing equipment and appliances, etc. Thank you. Dan.
The human body has a higher impedance to DC currents than AC, so this means that humans are able to withstand the effects of an electric shock arising from DC exposure much better than when exposed to AC Alternating current (A.C) is five times more dangerous than Direct current (D.C). The frequency of the alternating current is the main reason for this severe effect on the human body. ... At this frequency, even a small voltage of 25 volts can kill a person.
muhammad muneer ahmad malik the human body has a bit of capacitance, if you know how the to calculate that capacitance into your body's impedance you'll see that for the same effective voltage, your body will have more current with AC going through it than DC.
ragenFOX Think about it. When Tesla and Edison were battling it out Tesla was promoting AC, so Edison went on his tour killing animals with AC, but the science won out proving AC was safer, thus our houses are all run on AC.. DC is more dangerous.
Robert Matthews safer for fires, arcs, and whatnot, but not safer when living things get electrocuted. as i said, human bodies have capacitive properties, so when applied with AC voltage, the effective current is higher in AC than DC. you can test it your self, or look up people who have tested it on their selves. and if you think that this is crazy, go study AC circuits and Capacitive reactances.
Both are equally dangerous. Most DC circuits do not exceed 100V so we don`t necessarily think them as being as dangerous. Either way current kills and both AC and DC have the potential of deliver fatal amounts.
I'm a mechanical trades person who's in power station shut downs for years on Generators, steam and gas turbines and I know swat electrickery. Awesome video and as the head says " How to use a multimeter for beginners"
Brad b Awesome! I'm looking at getting into electronics and need a good/reliable tool. Could you recommend a good multimeter (no more than $50)? Thank you.
+Thatoneblackguy258 I don't own one myself but I need on for mechanics and the ones they use in college are pretty reliable. I will probably get mine from halfords(uk) for like £20. they sell them on Amazon
+Thatoneblackguy258 Fluke is one among the best you will buy one and it will last your lifetime the entry fluke level are made in china a better one made in USA for a professional tech use is around $700.00 to $800.00 at that price they are bomb proof water resist and are often use in industrial use ..if you buy a cheap one around $20.00 you will have to buy a new one every two years..
He asked "which is more dangerous?" The answer is obviously they are both equally dangerous. They will both kill you. A wise man once told me, as I looked in amazement at an electric fence and read '10,000 volts': "Son, it ain't the volts that kill you. It's the amps." Alternating Current, otherwise known as AC current is just a more efficient way to carry power without loss. It doesn't mean it's more dangerous. Always take proper precautions when dealing with electrical situations. Remember, even a little 12v battery has enough power to stop your heart, given the right situation. Have fun juicing :)
i have used your video to help educate RV people that need some basic information..... well put together all my friends have appreciated this educational video.... unfortunatly a lot of people who get into RVing have no clue between AC and dC ...much less trouble shoot...nicely done

Hi from Cape Town Martin!
Thanks so much for creating the content that you do. I have been a Software Engineer for about 15 years, and am only now starting to venture into the hardware / electronics side of things.
I have watched a number of your videos on my journey of learning electronics, and they are always clear, concise and very informative. I especially like that you put an important emphasis on safety. Way too many cowboys our there making things look quick and easy. I much prefer getting a thorough understanding, including of all risks involved, before diving into an activity.
Anyway, just wanted to give you a quick work of thanks for the work that you do, it is helping me and other beginners across the world a great deal :-)
Cheers
I am in the U.S., the way you use water compared to electricity is great!!.. I am doing online training to be an RV technician.. very helpful.. will be watching the rest!! Thanks again for the information!
Your videos are Great! very easy to understand and follow. Thank you!
Rodolfo Varela My pleasure, thanks for the feedback.
I really do like how you simplify & demonstrate your breaking it down for the common clown like me. L.O.L I wish all others would do the same for making it understandable for the common Joe & talk in laymen terms & bring it down to earth. The problems w/others is they want to sound sophisticated & complicate it. I call this prestige or job insecurity for they have an issue w/an inability to relate w/others.
Now I know a little more about how to use my multimeter sitting on the shelf! Thanks for the basic tutorial!
The teacher Deserves some Thumbs Up👍👍👍👍 I have learnt A whole unit in 30 seconds Wow!
So many "experts" forget they had to learn too. Really good show. Thank you.
Very helpful, helped me get back to being familiar with a multimeter again. Good job.
For anybody wondering about the question: DC is almost always more dangerous to workers, not because it's inherently more powerful, but because of the difference in physiological effects between AC and DC. The nice sine wave of AC current, indicating that the current reverses periodically, means that when you become a current path, your muscles will contract when the current nears either maxima, and relax as it approaches 0. That means that whatever you were doing that caused you to become the current path, you can stop doing (drop the wire/tool). With DC, your muscles just contract and that's it. You have to just hope that your life doesn't depend on being able to release something, because that ain't happening. I haven't watched the next video yet but I'd bet that's more or less what is said.
It's much easier to get pulled off if it's AC. Even a woman could do it.
good info! sounds like a good interview question.
50Hz in Australia, pretty sure 60Hz in America. AC alternating from +180 degree / -180 degree of the sine wave at 50/60 times PER SECOND....... AC is always more dangerous. Taking holding on to the conductor out of the equation, it is the pulsing that completely fucks up the human body.
A very simple google search can confirm this, the number of people saying DC is more dangerous is worrying and i hope you aren't all in the electrical trade.
@@kcuhc84 *_Even a woman..._*
Great Scott! I didn't realize people were still using this phrase.
@Nick Cranston In the 20th century, they taught in schools that DC was way more dangerous. What they taught took several weeks to explain, which makes it hard to accept a 3 second contrary explanation.
your a gifted teacher sir,thank you,your really empowering people,it's a lovely gift to give. ;0)
I wouldn't be surprised if this guy taught at tech; school, i would class myself as not knowing anything about electricity, however after watching 1 video i now understand voltage a lot more clearly----THANKS HEAPS
I am a beginner to Voltage Meters and I thought this was very informative. Also thoroughly explained. I liked the video and instructional aspect a lot.
Love it. Clear and understandable. Thank you!
Thank you for the information on this lesson.very clear on the lecture.lots of questions were answered.
Your tutorial video is still helping people in 2020! Thank you.
hi Martin, You tutorials are fantastic. I am studying HVAC and the guy in the college lectures is by a long way very confusing. (Im British living in Chicago (Accent is killing me)) I can understand you joyfully .. I think you are saving my skin with your tutorials... Thanks you're a star
Thanks alot i managed to learn more on multimeter, 11 years down the line and the content is on top🔥
Great tutorial, Thanks!
Keep educating!

He is just propagating for fluke through teaching !
No wrong in educating folks.
Excellent. Thank you for the effort you put into this. The actual explanation of the various aspects of electricity makes the biggest different for newbies.
All of you engineering experts giving the uploader flak for being "too informative" need to realize that all the info is there to cover everything. You might have the advantage of a good father figure in your life to teach you these things, or a good school system, but not me. I didn't know shit but thanks to this video I do. It doesn't take an expert to learn this, just as it doesn't take a complete moron to look for this video.
Very true, my father didn't taught me anything, he only put fear and doubt in me for ever wanting to learn things, so videos like that are so awesome to close the gap
Well said! I definitely learned a lot. The basics really do help since I am a novice and just looking to start a new project during this quarantine. Gotta learn something new to keep myself busy! Thanks for the video!
@@Tal.10 heeey sounds like my father, such pity, we could have had fun
@@mustang19ms I hear you buddy, today i try to teach my kids to be the complete opposite, it's the fear of failing that holding us back, but if you want to learn and grow you have to try and many times fall on you'r ass till you get it right, i'm telling them if you didn't fail at least 5 times a day don't talk to me :)
Ikr? I just did a rant at my 20 year-old about how can they not be teaching this stuff in school.. It's more useful than how to bake a cake, yet they still teach that,lol. I have a similar rant I roll out now and then about why they don't teach stock market investing in high school. We need to equip kids for real life imo.
Thanks so much for your video, I've been left in a weird middle ground. Previous jobs have given me experience but no understanding (think colour by numbers, SOPs and step by steps) I'm now working a better job but I looked a right melon using a multimeter. My favourite line was "lift the that tray with your fingertips, there's a big transformer on the other side"
I am taking CompTIA A+ and it was time to use a volt meter. I have not used one since I was a kid and my dad tried to show me. This video exceeds my expectations for a beginner learning to use a voltmeter!
That was a very good demonstration. In essence.
Lol. I didn't get it until I watched a little more of the video.
I would say. In essence
This video was AWESOME!!!! THANK YOU!!!! MY answer to your question is DC, because it is DIRECT current, meaning the current is straight through, vs. AC which is alternating current and is like an on/off switch or a high/low switch...? I guess II'll see on the next video! :-)
Amazing explanation, thank you!
Very informative. I have learnt something from an 8year old video. Good instructor
Very helpful tutorial, thankyou.
Just starting in this new field, planing to buy my 1st Meter, wached your video on fluke 107.
Got first two project today.
1. Measuring DC voltage.
2. Measuring AC voltage.
Great Multi-meter for beginners guide....had to install a light didn't want to kill myself, bought a multi-meter and looked for a guide and found you. My multi meter looks nothing like yours aka cheap, your in-depth guide was perfect. Even though my Multi-meter was set up different you explained the differences between them very well and I was able to test a live wall jack without getting crispy (always a +) in the process. Light was installed I survived to make this comment and can check batteries to boot which came in handy this morning. Good work.
Very nicely explained. Thanks
Is the fluke 117 good?
@@marcomizzoni8323 yes
The teacher Deserves some gifts for the well done job

Thank you for this excellent tutorial ! On another note, what would happen if I measure a DC voltage with my multimeter in AC mode and visa versa? Would I run any risk? Hope you can answer, thanks !
thanks so much! amazing explanation. I am a mechanical engineer, so appreciated the pressure/volume flow analogies! Spent quite a few years living in SA - great country.
Dear Lovely brother Mjlorton, Thank you for the above. Now I know a little more about how to use my multimeter sitting on the shelf! I am asking God to be with you all the time and protect you from bad things with your family members.

don't you just love our South African accents? thanks for the video this is amazing!
I was most surprised by the south African electrical strip! that looks way different than what we got in the 🇺🇸
I bless the rains down on Africaaaaaa!
would like to see the set up on how you brighten and dim led
Brilliant Channel spent 3 days watching before deciding on a Agilent Meter thanks a million
Highly instructive methodology. Your introduction was quite clear, starting from a very simple idea of water flowing from a horse pipe connected to a tap, so brilliant. The pace of explanation,step by step and use of simple language vocabulary makes it much much easier for beginners like me who are interested in electricity. I need to watch more and more video tutorials on your channel.
Keep it up my "Super Instructor".
16:29 I thought it shows 1.191 volts, not 1.91 volts?
he just mispoke the next sentence later he basically corrected himself by saying it rounds up to 1.2 volts
Even though it's great information I think an entry level meter would be the three plugged one mate. I personally think you should have done your demo for beginners on one of them
30:44 "And now I've gone and blown it" :D
Man you are a gifted teacher bro. Keep up the great work
Excellent video. I have not gotten full use of my meter and your videos are showing me other ways I can use for testing equipment and appliances, etc. Thank you. Dan.
DC Power is more dangerous because it holds you tight, while AC will release you after half frequency time.
The human body has a higher impedance to DC currents than AC, so this means that humans are able to withstand the effects of an electric shock arising from DC exposure much better than when exposed to AC
Alternating current (A.C) is five times more dangerous than Direct current (D.C). The frequency of the alternating current is the main reason for this severe effect on the human body. ... At this frequency, even a small voltage of 25 volts can kill a person.
DC power is more dangerous then A.C. because D.C is the direct current and there is no cycle of changing polarities in D.C. thanks
It's a trick question. Both are as dangerous as each other, both can kill.
Yes both can kill i understand but logically D.C is more dangerous because of its continuity. i agreed with ur killing philosophy. thanks.
muhammad muneer ahmad malik the human body has a bit of capacitance, if you know how the to calculate that capacitance into your body's impedance you'll see that for the same effective voltage, your body will have more current with AC going through it than DC.

Think about it. When Tesla and Edison were battling it out Tesla was promoting AC, so Edison went on his tour killing animals with AC, but the science won out proving AC was safer, thus our houses are all run on AC.. DC is more dangerous.
Robert Matthews safer for fires, arcs, and whatnot, but not safer when living things get electrocuted. as i said, human bodies have capacitive properties, so when applied with AC voltage, the effective current is higher in AC than DC.
you can test it your self, or look up people who have tested it on their selves. and if you think that this is crazy, go study AC circuits and Capacitive reactances.
Entry level? The Fluke 177 costs over £200!
Staying alive is expensive
My entry level meter is a 1$ Chinese multimeter

Very helpful indeed. As a total novice, I've been intimidated by multimeters due to not understanding them. This has been a great introduction.
Nice one buddy...im not good in english, but yr word easy to understand and very clear, tq much
AC can kill you but remember it is not the voltage it is the Amps that can cause death ⚡️⚡️💥💥
I wish there was an easy way to remember this because i always mix amps up with volts ...
Both are equally dangerous. Most DC circuits do not exceed 100V so we don`t necessarily think them as being as dangerous. Either way current kills and both AC and DC have the potential of deliver fatal amounts.
Amperage kills, not current.
John Gray they are one in the same..
Yes, meant to say voltage.
A/C is more dangerous. Let's not be silly here with the facile equivocations.
DC voltage is frequently 300 to 800 volts and beyond.
I'm a mechanical trades person who's in power station shut downs for years on Generators, steam and gas turbines and I know swat electrickery.
Awesome video and as the head says " How to use a multimeter for beginners"
The best explanation of multimeters I could find on the web!
$300 for an entry level multimeter?!
You can get decent ones that work all the same for $30
Brad b Awesome! I'm looking at getting into electronics and need a good/reliable tool. Could you recommend a good multimeter (no more than $50)? Thank you.
+Thatoneblackguy258 I don't own one myself but I need on for mechanics and the ones they use in college are pretty reliable. I will probably get mine from halfords(uk) for like £20. they sell them on Amazon
+Thatoneblackguy258 Vichy VC99 is pretty much unbeatable under $50
+Thatoneblackguy258 Fluke is one among the best you will buy one and it will last your lifetime the entry fluke level are made in china a better one made in USA for a professional tech use is around $700.00 to $800.00 at that price they are bomb proof water resist and are often use in industrial use ..if you buy a cheap one around $20.00 you will have to buy a new one every two years..
He asked "which is more dangerous?" The answer is obviously they are both equally dangerous. They will both kill you.
A wise man once told me, as I looked in amazement at an electric fence and read '10,000 volts': "Son, it ain't the volts that kill you. It's the amps."
Alternating Current, otherwise known as AC current is just a more efficient way to carry power without loss. It doesn't mean it's more dangerous. Always take proper precautions when dealing with electrical situations. Remember, even a little 12v battery has enough power to stop your heart, given the right situation.
Have fun juicing :)
I'm going to call BS that you need a $160 meter for "entry level"
+MJmichand The one in his hand, I have here at 300 clams. It's the 177 w/ 4 terminals. I think the buck sixty one has three.
Excellent video and much appreciated 8 years on from the original series posting - Many thanks!
i have used your video to help educate RV people that need some basic information..... well put together all my friends have appreciated this educational video.... unfortunatly a lot of people who get into RVing have no clue between AC and dC ...much less trouble shoot...nicely done
1.19v not 1.9v
