Well I wish there was a grading system for teachers on RUclips, paired to a function to filter by grade. This way we could immediately bypass all the wannabees, time-wasters, and just crappy instructional videos and go directly to highly efficient, knowledgeable, and entertaining instructors such as this gentleman right here. Congratulations on the delivery, you're awesome and I hope you teach for a living.
It's crazy how much easier you have made me understand this topic much better and efficiently than my professor at a university did in a semester. Thank you.
So...basically...i love your teaching method. It keeps me laughing while i'm understanding and absorbing the material. It's great. I appreciate this a whole lot more now.
I was taught OHMS LAW when I was a child by my father. He wanted me to get my ham license. I've found that problems like this become so much fun to figure out. I don't get enjoyment out of many things, but this is one. I absolutely love your teaching style Doc, hat's off to you.
7:14 ; he only calculated 1/((1/5)+(1/30)+(1/10)). Since the formula for calculating parallel resistors is (1/R total = 1/R1 + 1/R2; when R1, R2,.... are all parallel resistors). So put that into a calculator and u get 1/(1/3) which equals to 3.
Similar story with me, although I was the one who wanted my ham licence. My dad happened to be a senior electronics engineer for a big company so he taught me all I needed to know. I got my ham licence at 14.
As a child i got enjoyment out of 3 Flavoured Neapolitan Ice-Cream (Choc, Vanilla, Strawberry) Covered (and.. I mean fucking drenched) in Ice magic Mint Choc topping I mean... Ohm's law is pretty cool as well but Ice Cream in chocky topping............ Ohhh it's a bit better
I have to say, this is the best explanation of circuits I've ever watched. I'm a senior in AP Physics right now and I've been struggling to understand what was even going on, and this video broke it all down so that anyone could understand these complex problems. Thank you a lot and I will be sure to recommend your videos to all of my classmates who may be struggling.
You are the only academic youtuber which i can actually sit through and watch a video that is longer than 10 minutes, and actually learn what I came here for plus more. Thank you SO much!
this 24 minute video has taught me more than all of my lectures on this subject combined. Thank you so much!!!!!!!!! now time to cram for this test in two days
Thank you so much for this video. My AP Physics teacher is terrible at explaining things and not a friendly, helpful person to go to for help at all, so I've been trying to learn the concept on my own. I haven't been able to grasp it until I watched your video so thank you for posting such a wonderful study aid.
I am watching this video at 3:17 am for my final this morning at 9, and this guys enthusiasm kept me awake the entire time, and trust me I never stay awake during any of my profs lecture, they bore me to death
Long-time student here, this is a great video. I still always appreciate an entertaining and engaging presentation of concepts, and you nail it. Thanks for offering such a great service, and your students are very lucky to have you!
I love your confidence and the personality that your using to teach. If at least half of my professors were like you i would be able to enjoy my college life and academic progress fully.
This video was the switch... That closed the circuit... Which flowed through a resistor... Inside the light bulb... Over my head. At least as far as the equivalent resistance in parallel resistors is concerned! ;) Thank you so much for the help Doc!
You have singlehandedly saved the day! I really understand the differences between series and parallel circuits now! I appreciate your time and effort of this video!
ive been stumped by this for days and now i think i know why i wasnt subtracting the voltage drop from the total voltage thanks! you explained this way better than my shitty textbook.
i really liked his videos so much that i started watching all his videos.his teaching method is really helpful. before watching this video i saw a lot of videos bt i was not able of understanding this bt after watching this i became skilled in this and i could even help my frndz in their probs.thnx 😊😊
I started in electronics somewhere around 1968. I do ok at Ohms Law but this guy is really good at explaining the basics and it is easy to watch and understand. Sir you get A+
I went through an electricians union apprenticeship for 5 years. The second year, we had to work with so many problems like this. I believe if I knew you had videos like this, I would have had a much easier time. I struggled for so long, and this video showed everything and explained everything in detail, and your voice isnt monotone, annoying, or hard to understand. Thank you for helping out this brain that has a hard time understanding anything lol
Doc Schuster Unfortunately my homework still doesn't make sense to me. However since I only have to combination circuits like this for extra credit I'm not worried.
You sir, are amazing! I spent hours struggling with my homework and getting all of it wrong. After watching this video, i went back to my homework and it just all makes sense now. I definitely owe you a dollar...
I'm taking Physics 2 in college and I cannot be more thankful for your videos! You make physics fun and exciting! Thank you for putting so much useful information, concepts, and approaches in each video!
can i just say thank you so much. i have been trying to find videos to help me with circuits and how they work and the calculations fit and im grateful i found your channel
And then... In only 24 minutes and 5 seconds. Everything I have been learing in physics for the last week or so was explained... You my friend... Are amazing... Your a great teacher! Thanks a ton for your help!
Making the simple stupid. This gentlemen has the gift of communication. He is capable to communicate with everyone at every level, and not only with the genius. A teacher is supposed to communicate like this; Bravo.
I’ve taken tests and failed them, I was trying to do the biggest equipment’ Until I saw ur videos, you took me to the smallest thing I can imagine’ ah resistor. Thank you so much, u were born to teach.
you dont need a calculator to calculate that its 1/R= 1/ (1/5 +1/30 + 1/10) now you introduce a technique called common divider , its the biggest divider , for this case its 30 ..like this 1/R= 1/ (1/ 5 x6 + 1/30 +1/10 x3) = 1/ (6/30 +1/30 +3/30) = 1/ (10/30) , so you can delete zero's and it looks like this 1/R= 1/(1/3) now 1/R = 1/1x1/3 , 1/1 x 1/3 = 1/3 so its 1/R=1/3 , now you can delete 1/ cuz its on both sides and what you are left with is R=3... only thing you needed there is a technique called multiplying by common divider , essentially to make numbers even you find the common divider so that you can add different dividers like 1/2 +1/4 + 1/8 its the same thing as 4/8+2/8+1/8=7/8 ... judging by the numbers used and how they all add up nicely i suppose you are meant to use that technique.. i was never good at math , i failed badly finel years exam , but at least i know how to add up those numbers without calculator :) i didnt even know that i still remember doing that in school
Never had such a beautiful Sunday morning learning so much of V=IR in one short 24 minutes lesson, and clears so many niggling confusion. By far the best video lesson. One dollar? Still don't mind, it's a valuable dollar. Better than the fees one pays for some courses. And not forgetting to mention that this video is almost 8 years old. 1.4m views.
Watched multiple videos before this one and none of them worked but this one did, you did a really good job on this, even though it was seven years ago, thanks.
+Martin Andrew Marc Ben Cool Story dude, can't believe you actually carried out your own investigations and questioned a calculator manufacturer. And learned how to evaluate the decency of a calculator (i still have my BODMAS theorem and 12x table in check, everything else i admit, i use the calculator!)
+Martin Andrew Marc Ben LOL, "Digital Motor" and "CINETIC" seriously?? Sounds like your mathhood were full of scammers. Right, keep the calculations coming
I'm in apprenticeship studying electrical engineering with no idea at all but this video helping me a lot...thank you so much for sharing your knowledge
Doc i have a test tomorrow on series & parallel circuits and so far the video has helped so much with my understanding on the subject. I really appreciate you making the video
tick tock. That is based on the murphy law of statement v. minimum practical outcome degeneration. Wherein a 15 min problem = 22.5 minutes to solve. A simple 1.5 : 1 ratio is applicable as the reality laden expected outcome v. original statement.. Another example would be like a half hour lunch break will always take 45 minutes. (30 x 1.5 = 45) This equation was originally formulated by murphy while he was having a good day, the ratio may actually have a weighted outcome value averaging of 2.7 : 1. Wherein a 15 minute problem will take 40.5 minutes to solve. The plus side of this is it is ok for your half hour lunch to take 1 hour and 21 minutes. Ex: 30 x 2.7 = 81 See how critical thinking skills will help you in your day to day. : )
Doc Schuster We all work against the clock...Doc. I'm with ya, not against ya. I hope you're not using (Terry Lang), as the name...hmmm. I meant to prove that by making up that rhetoric concerning Murphy. But seriously, Doesn't every 10 minute project take 27 minutes ? LOL "Murphys Law of Statement v. Minimum Practical Outcome Degeneration." personally, now, after saying it for the second time. I like it. : )
Doc Schuster I've done some more real heavy thinking : / on this, and I will not surrender this to Murphy. I copyright this written law as Langwich. A term derived of My name, language , languish, and a sandwich. Langwich, pseudo intellectual property of Terry Lang 2014. now it's legal. ; )
I really really really hope that I watched this when I was 14 years old when I had my science exams.. now I'm already 20 and in Uni, and I finally figured it out all thanks to you!!! My kids will go on to benefit from this I guess.
I know it's 7 tears old but amazing video, thank you! This helped me out tremendously with senior high school physics during online learning in this pandemic. Entertaining, very easy to follow, well articulated, and aesthetic. Couldn't have asked for any better!

Danny MacDonald You're really nice! That would be a good system for students. Suggest it to youtube! I am a teacher by trade, in fact.
Doc Schuster
Hey Doc...do you have any videos on thermodynamics ?....phase changes, steam tables etc ?
Danny MacDonald
You bet! Check out my video index. I love thermo!
Loving Indians goes without saying! If that's not immediately obvious, you must not know any!
Doc Schuster awesome vid mate, do you have any calc vids?
It's crazy how much easier you have made me understand this topic much better and efficiently than my professor at a university did in a semester. Thank you.

Doc Schuster how did u get 3? help me pls
7:14 ; he only calculated 1/((1/5)+(1/30)+(1/10)). Since the formula for calculating parallel resistors is (1/R total = 1/R1 + 1/R2; when R1, R2,.... are all parallel resistors).

Learned more in the 24 minutes that it took me to watch this video than I did from my professor this semester. Thank you.
Thank you so much! I'm in my first year of engineering and have a test coming up and you just made it so much clearer! We need more people like you!

This was super helpful man! You're a way better teacher than most who work in high schools! Thanks a ton
This video is by far the best I've seen for circuit analysis !!!!!!!
I live in England and couldn't find and useful videos from over here to help with physics but this helped so much, thank you.
This was so helpful. My professor did a similar problem in class but left out a lot of the explanations. I am so glad that I found this video.
Steps are clear and easy to follow. Awesome teacher!
I love your confidence and the personality that your using to teach. If at least half of my professors were like you i would be able to enjoy my college life and academic progress fully.
This video was the switch...
That closed the circuit...
Which flowed through a resistor...
Inside the light bulb...
Over my head.
At least as far as the equivalent resistance in parallel resistors is concerned! ;) Thank you so much for the help Doc!
David Porter HA! Glad it helped!
My dude, I've been locked in my room for a week just trying to piece it all together. You're a lifesaver. Keep up the awesome work bro
You are my hero. My physics teacher just cannot explain so thank you.
Thanks, Anne. I hope I can live up to your expectations!
Omg ur hot
Thanks for well explanation about ohms theory
Probably one of the most thorough problem explanations I've ever seen. Bravo Sir, Bravo.
You are amazing. Thank you for teaching me what my professor could not.
Ashtyn Greenstein sure #InterestingElectrical
You have singlehandedly saved the day! I really understand the differences between series and parallel circuits now! I appreciate your time and effort of this video!
Great Video, Doc! wish more teaching was done like this :)
This may be the only video I've seen that educates just as well as being comedy gold. Well done.
I enjoyed this and understood it much more now than I did back in physics class
Can't thank you enough. Have a test over this stuff tomorrow and had no idea how to solve these until I watched this video. Very well done!
you have taught me more than my physics teacher wow thank you so much
What a fantastic, no brilliant Web site. made out to be understood. You can be our teacher anytime.
i learned more in these 20 minutes than what the teacher in zoom tried to teach for 3 hours
This video has heed me so much, I think i've seen it 5 times over the course of three years now. I am so thankful for its existence.
ive been stumped by this for days and now i think i know why i wasnt subtracting the voltage drop from the total voltage thanks! you explained this way better than my shitty textbook.
I wish I had a Physics teacher like this guy. We had suckers back in the day. Full marks for the delivery
MATE!!!!!
You made it so easy to understand :) always struggled with this. but thanks to you I think I can find my way around it.
Cheers...
This is literally the first time I wished there was a 5 star rating system on RUclips cuz this guy deserves waaay more than a sub and a like
i really liked his videos so much that i started watching all his videos.his teaching method is really helpful. before watching this video i saw a lot of videos bt i was not able of understanding this bt after watching this i became skilled in this and i could even help my frndz in their probs.thnx 😊😊

This is the single best Electric Circuits video I have ever watched.
Not to mention you're a pretty funnny dude!
Im actually learning! trying to study for my advanced ham licence and its difficult making sense from just reading notes. Keep it going Doc! Thx

You are an excellent teacher!
Thanks, yo. I try my best, anyway.
By far probably the best tutorial I ever came across. It was to the point, and clear. Thanks!
I did one! Just make sure you search with Kirchoff (two f's). Thanks for your support! Enjoy.
I have been watching many of your physics videos lately, and I just wanted to say that I appreciate what you are doing. Thanks!
So we're not gonna talk about that beautiful blue marker?
+mylobage let's discuss it over the next few weeks
+mylobage thats just a regular blue marker under a crappy camera
This is the first time I've ever understood what voltage drop was and what stayed constant when solving for voltages and currents. Thank you so much!
Thanks a lot mate:) you actually make physics so fun.
I love it! I'm glad you're having fun, too.

Way better than any physics teacher I've had, Good job!
You are my college physics lecture. Bless you
rob b meh, people suck in general, let them do it however they want
You're infinitely better of a teacher than my college physics professor. Thanks a lot!
The Moon Babies Did you divide by zero? That's more of an insult to him/her than it is a compliment to me. But..thanks?
this was really helpful, thank you so much. may God bless you.
And then... In only 24 minutes and 5 seconds. Everything I have been learing in physics for the last week or so was explained... You my friend... Are amazing... Your a great teacher! Thanks a ton for your help!
I wouldn't do all that for a dollar. It would have to be at least a dollar fifty for it to be worth my time!
god bless you man!!!!!!!! i have been struggling so much with series parallel circuits until i came across your video. thank you so much.
You are so funny! This video helped a LOT, thank you
I'm glad you liked it!
That's how to hook someone in to watching your videos. You explain stuff super interestingly, and I hope you make more
so much work for a dollar :/
Vorrtekks These are hard times!
lmaooo, ikr keep your dollar
He didn't get the dollar. It took him longer than the allotted 15 minutes.
That was money well earned, especially for the knowledge given! Digital Dollars!
Well can be done in 2-3mins *MAX* if you know the concept be4 hand
Making the simple stupid. This gentlemen has the gift of communication. He is capable to communicate with everyone at every level, and not only with the genius. A teacher is supposed to communicate like this; Bravo.
lost it at anarchy meter - what would be unit of measurement for such a device?
+Steve Smith Probably # of fucks given?
+Steve Smith probably some derived unit of human entropy/stability.....don't ask how that would be measured
i love the way you teach. i wish all teachers are like you
His voice sounds like deadpool.
EXACTLY WHAT I WAS THINKING
I did physics 40 years ago. An excellent 1st class recap. Got it in one!! Thank you.
I would have ended the video with a dollar smacking that table! BOOM!
***** That's a solid ending! I should ask you to design the punchlines for my videos!
haha...sure. I was waiting for that dollar to come out, but it never did :-(. Your stories make the videos more interesting.
I’ve taken tests and failed them, I was trying to do the biggest equipment’
Until I saw ur videos, you took me to the smallest thing I can imagine’ ah resistor. Thank you so much, u were born to teach.
you dont need a calculator to calculate that its 1/R= 1/ (1/5 +1/30 + 1/10) now you introduce a technique called common divider , its the biggest divider , for this case its 30 ..like this 1/R= 1/ (1/ 5 x6 + 1/30 +1/10 x3) = 1/ (6/30 +1/30 +3/30) =
1/ (10/30) , so you can delete zero's and it looks like this
1/R= 1/(1/3) now 1/R = 1/1x1/3 , 1/1 x 1/3 = 1/3 so its 1/R=1/3 , now you can delete 1/ cuz its on both sides and what you are left with is R=3... only thing you needed there is a technique called multiplying by common divider , essentially to make numbers even you find the common divider so that you can add different dividers like
1/2 +1/4 + 1/8 its the same thing as 4/8+2/8+1/8=7/8 ... judging by the numbers used and how they all add up nicely i suppose you are meant to use that technique.. i was never good at math , i failed badly finel years exam , but at least i know how to add up those numbers without calculator :) i didnt even know that i still remember doing that in school
Cray cray
Never had such a beautiful Sunday morning learning so much of V=IR in one short 24 minutes lesson, and clears so many niggling confusion. By far the best video lesson. One dollar? Still don't mind, it's a valuable dollar. Better than the fees one pays for some courses. And not forgetting to mention that this video is almost 8 years old. 1.4m views.
This video made me more confused than I already was
This is just a worked example. You should watch the one called series and parallel DC circuits intro - it might help.

Doc i have a test tomorrow on series & parallel circuits and so far the video has helped so much with my understanding on the subject. I really appreciate you making the video
you didn't solve in 15 minutes :P
tick tock. That is based on the murphy law of statement v. minimum practical outcome degeneration. Wherein a 15 min problem = 22.5 minutes to solve. A simple 1.5 : 1 ratio is applicable as the reality laden expected outcome v. original statement.. Another example would be like a half hour lunch break will always take 45 minutes.

It is most excellent to have a name for my temporal failings!
Doc Schuster We all work against the clock...Doc. I'm with ya, not against ya. I hope you're not using (Terry Lang), as the name...hmmm. I meant to prove that by making up that rhetoric concerning Murphy.
But seriously, Doesn't every 10 minute project take 27 minutes ? LOL
"Murphys Law of Statement v. Minimum Practical Outcome Degeneration."
personally, now, after saying it for the second time. I like it. : )
Doc Schuster
I've done some more real heavy thinking : / on this, and I will not surrender this to Murphy. I copyright this written law as Langwich.
A term derived of My name, language , languish, and a sandwich.
Langwich, pseudo intellectual property of Terry Lang 2014. now it's legal. ; )
Nice. Now I'm wondering what type of sandwich was on your mind that could be worth a dedication.
this is a very interesting video; his method of teaching is simliar to my teacher ironically. definitely deserves a like
You're hilarious.
I really really really hope that I watched this when I was 14 years old when I had my science exams.. now I'm already 20 and in Uni, and I finally figured it out all thanks to you!!! My kids will go on to benefit from this I guess.
xoxoxoifyify That made me smile. Thanks!
i srry u didnt get ur dollar bc u went over 15 mins
I know it's 7 tears old but amazing video, thank you! This helped me out tremendously with senior high school physics during online learning in this pandemic. Entertaining, very easy to follow, well articulated, and aesthetic. Couldn't have asked for any better!
lmao anarchy meter..
It's 2021,i have physics final next week and this is the only physics channel i enjoy watching
Why waste my time for one freaakin dollar
Thank you so much, Doc! This will hopefully save me for my test tomorrow. Learned far more in this 24 minutes than in 90min in class.
I wish teachers wouldn't take things so seriously, and be more like this guy haha
You are a great teacher! Love your enthusiasm and how fast you were.
