- This physics video tutorial explains the concept of basic electricity and electric current. It explains how DC circuits work and how to calculate voltage, current, and electrical resistance using Ohm's law. In addition, it shows you how to calculate the electric charge and the number of electrons flowing through a wire at any given point. In addition, it has a few examples and practice problems on electric power, cost of electricity in Kwh and other stuff as well. It provides visual drawings, equations, and formulas as well as the units of common variables that you'll encounter when dealing with electricity. It discusses the difference between conventional current and electron flow. The unit of electric current is the ampere or amps for short. The unit for resistance is ohms and for voltage is volts. 1A is 1C/s or 1 coulomb per second. Electric current is the rate of electric charge flow. Charge represents the quantity of electrons in the case of metal conductors. The unit of power is the watt which is 1 Joule per second. Power is the rate at which energy is transferred. Equations used include V=IR, P=VI, and Q=It.

Thanks. I just learnt more in 18 mins than I have learnt from my teacher this entire term. Also I have my exam tomorrow so even bigger thanks
I have a guestion uhm where are you from and how 's the education system in your country?
i would have liked the comment but i didn't want to ruin the "222" likes
My qstns are way more complicated than this. I feel like this is just on how to use formulas.
Hey Bro You're not alone :D
@@rafimohammad5907 what syllabus are u studying
Remember to like this mans videos. Dude gives FREE education thats often taught better than my college classes (which cost hundreds, sometimes thousands, excluding scholarship funds). OCT deserves the support.
This guy is the goat
You're learning year 11 physics in college?? Alright lmao
@@jacobschmitt7033 Hey man, sorry about my comment. Maybe it was a little insensitive. my bad
@@eeehhelp424 not all education is the same across the globe, your highs school curriculum might have been different than his, also i am currently learning this in college as physics 2/calc based as prep for engineering courses down the road.
@@eeehhelp424 we're learning this in grade 9...
Who has a test tomorrow? 😂
I have a test in two days

Douche Bag at georgia tech by any chance?

You’re better than my teacher at teaching. Instead of teaching us, she talked about how she got divorced and the “journey” of 5 years.
Bruh moment right here
Kkkkkkk really
Imagine😭
dude my teacher just puts a powerpoint up for us and expect us to get everything
lmao
I'm an old engineer who hasn't had the need for this stuff for years due to the kind of assignments and opportunities that were offered to me out of school. Now I'm refreshing my old self. It's so weird to see stuff that I learned 20 years ago just pop back with a little nudge from these videos. A great way to learn or relearn.
Dude when I become rich I’m gonna make you a millionaire u saved me too much
Did you become millionier now
@@SYCOGAMERZ he said "when" it's been like a year man we gotta be patient
@@SYCOGAMERZ It's been only a year man, wait like maybe 10 years...?
I wish you great prosperity in your endeavours
@@fortnox5e1h73 yeah
We're having a quiz tomorrow and I didn't listen to my teacher...so here I am trying to learn it by myself ahhaha
Just wanna tell you. You literally saved me from dropping out. Thank you.
hope u dropped out lolz

My go to channel whenever I have an exam the next day!!
WHY AM I ALWAYS HERE WHEN I HAVE A TEST TOMORROW
I just spelled you words as if youre screaming omg 😂😂🤣
Omg same, I literally have a test in 8 hours, it’s currently midnight
@@anthonybawia99 same
What grade are you guys? I am curious in what grade other students study electric current and stuff.
@@salutboss3008 Im in 9th grade. Im from a pretty small country in northern Europe. Latvia. What about you?
I would like to thank you good sir for all the help through all these years, you are why I received A's in physics
I should have paid more attention in physics class
I'm actually a Turkish student and I hate physics. But english is my favorite lesson so I decided to combine the two. And it worked. Your video was very understandable for me. Great work!

doctor u SAVED MY LIFE!!! i was struggling with this lesson,,, i've viewed more than 20 videos on this part and with no use!! Thanks
2024 anyone??🎉❤
Yep, I probably need to work on how to draw and work different challenging circuits, confused, test this Friday 😢😅
Thank you, missed class for a new student conference and you're a lifesaver.
Thank you so much! You are a life saver. I've always had a problem with understanding electric current and it's physical properties but your explanation is absolutely perfect! I finally understood this lesson. Thank you for making this wonderful video💜
Electric circuit is not to hard if you put your focus in it 😎
any1 watching this in 2024 😅😂
Brooo
Yess
Whaddup
🤘🤘
This video basically covered 2 chapters in my textbook! Damn helpful and thankful 🙌👏🙏
Im pulling an allnighter right now for my Physics exam tmrw.
How did it go
same
How’d it go
Mr. Organic Chemistry Tutor, thank you for an outstanding video/lecture on Currents, Voltage, Ohm's Law and Basic Electricity. This is a solid starting point in Electrical Engineering.
I've got term exams tomorrow. these videos are saving my life :D
I have been trying to understand this since i was at the ordinary levels. Haven't watched it yet but i have no doubt is just what i need.
thank u sir.
If I may
What country are you from?
Same bro o level

Sorry for the late reply
is anyone else triggered by how he says coulombs
I have never been more outraged.
I thought I was the only one , he says it like “column”
It sounds weird
Matt Spak that’s how u say it tho
Dipesh Maisuriya I thought it is ku-loms
Thank you so much! You're an absolute legend! I have a Unit 1 and 2 Exam for Physics, and your videos really helped me recall some of the key concepts in detail.
Thanks. I just learnt more in 18 mins than I have learnt from my teacher this entire term. Also I have my exam tomorrow so even bigger thanks,
At 8:09, we can use P=VxV/R(power=voltage squared divided by resistance in ohms). THANK YOU.
Fantastic video. Increase the voltage will AUTOMATICALLY increase the current
which will increase the available Power (watts) given the same resistance. Ohms law.
I love your class! Thanks for always saving me when I don't understand anything
Thanks @organic tutor.
Been one of my best mentor all this while.
How can I be like you sir 😀
Finally i understood this lesson🙂
have a test tmmrw :)
im gonna study using just your videos for a test i have on monday. will reply with my results!
I got an A+!
This guy is helping me make my CA # test in two hours
What a nice tutor
He teaches more than our teachers
U literally saved me from failing my end of year exam thx dude ☺️☺️☺️
Man english isnt even my first language but this man explains so good i understand everything
I’m here at 2024 and I’m having test today 😭😭
I got one tmr lol
How was it?
Thank you. I have a test based on electric circuits... It is so helpful.
Im so grateful for this channel 😩🙏🏽❤️
Thanks I think am ready for this exam🤞🤗
Thank you so much I have a test tomorrow so i thank you very much Iam going to watch more of your vids on later tests
oh
i didnt realise how easy this is...nice work
Wish me luck for my 2020 cies. I need those prayers😵🙏
You saved my life, thank you!
reading it from the book makes me want to lie down and sleep forever but after seeing this video i didnt realize it was so easy thanks tutor and thank God😭😭
Thank you so much for the video its really help me in learning about my 1st chapter in class electrical
Hi,
Earlier you said resistance and power should be balanced, but in the 4th problem P and R are not equal. Could you explain why? Thank you
Edgar Marquez He said the amount of power Created should be the same amount dissipated by the resistor NOT the resistance and Power should be the same.
Thanks alot.... Digital learning is far more better to understand rather than reading and learning... Thank you
I always go here when i don't understand the topic well and i think i made the right choice. Thanks man
This is an amazing introduction, thank you very much sir. This definitely helps!
Tnx man. It was simple the way you explained it. Keep on the good work cause I really appreciate it.
thanks a lot dude ..Its the first and last test of 8th grade..we have never had a test in physics and the first time we have I don't wanna fail..and you teach sooo damn well...btw you know the physics teacher sucks
Thanks
Very helpful thank you
Use triangles when using equations, a lot easier
At question 3, aren't you supposed to first turn the 1.8 W per second into per minute, and then into per hour and then into per day and so on? Because the answer I got I think makes a little more sense, which was $513.22 per month
retweet
You are simply wonderful, my friend. It is so impressive that you have such vast knowledge in so many subjects. You have helped me here as well as with Chemistry.
I appreciate you so much! Thank you.
this channel really helps a lot. honestly you make everything so much easier
These video help me to understand litte bit about electrical technology 😁
Electroboom should help
Good work men....
You'll helpin me alot
Thanks mate , Tomorrow I am having an exam on this chapter ... It helped me a lot ... SO thanks a lot .
The explanation is absolutely perfect🎉
can you do video about op amps (operational amplifiers)
Could you please upload more videos on Mesh Analysis, Nodal Analysis, Rectifiers, Diodes, Transistors, OpAmps, Combinational Logics, AC Circuits? It’ll be very helpful to all of the students. Thank you. 😄
english plz

How you understand!!!! its the hardest lesson I ever seen🙂💔
Wow this actually really helped!
my final exams tomorrow
Thanks so much for video 🙏🏼🙏🏼🙏🏼💪
I'm a third year Chemistry student and I been struggling with my physics course this semester. Thanks so much for the explicit explanation 🙏🏼🙏🏼❤️
thank u sir. U have helped me get As for the past two years
For question 3, do you not have to convert to hours from seconds? Isn’t a watt energy per second
yes, I noticed it too
Yess exactly!
The answer said KWH

Sameeee. I have my end of semester physics exam on Monday! 😭 I'm so cooked. 😂
Biology and Physics test tomorrow -.-
I pass the circuit test, because of you thanks Dude!!!!
your voice is so relaxing 🥰🤍
Who’s here cuz they have a test 😂
how can ıt be possıble ıf the cost of electrıcıty is $.11 per KWh? for a month that is $0.14, so meanless
Thank you sir ....
I love the way of your teaching
thanks pal, good videos, your maths could be more simple but they work, thanks again!
who knows dear Ryan from Nigaheega would only understand this part 4:33
Umm he sounds handsome lol
Alright so didnt understnad single thing today but came home and watched this. And did the whole assignment too (a small one tho). I have already said this a lot but again, thanks.....
thank you teacher amazing tutorial thanks
i will buy a mobile phone to you
still struggling with this: ' electric current, and circuits explanation thing.'
You are very clear, simple and coördinated I really appreciate you
I like how I'm watching videos about electrical circuits at night randomly
