thank you

Ur hot

I have my first A Level physics exam in two days and this video has helped me massively on a topic I couldn’t figure out for some reason

brother the electron are going the wrong way around the circuit

bro why are there vids more helpful than the books i am suppose to study

Thank you so much, helping me study/actually learn for my exam tmrw!

thanks so much life saver

Why 4A and 2A split at juction why not 5A and 1A.

I like your explanation sir

Nice Work mate

Thanks for posting. I have an EX-F1 and can't make heads or tails of the manual. This helps.

Can someone tell me what is the total current in this circuit please?

can you please upload again mate

@PeteGravell i have a question, what happens that in appertments, in a neighbourhood house the live wire is touched the earth wire due to some leak and in my house i am touching a surface of toaster and it's body is connected to the earth wire for safety. Now will i get the shock due to neighbour current flow in the shared Earth wire in the same multi story building?

stupid audio

i love you

Hi Pete. Interesting video. I have a question you may be able to answer. Can a single ball bearing be magnetized? And can it have a plus and minus polarity??

1000th like

Nice video (2 years since last comment 💀)

A LEGAND 🫡🤝

Well Explained. THANKS

In all my years of studying and teaching physics I've NEVER had to do a problem like this, and your example blew my brains wide open and saved my butt while I was teaching. Thank you Pete!!!

Is this how a railgun would function?

I have to congratulate you on the volume level alone, never mind the excellent explanation of Back EMF. The volume level, especially considering this is a 6 year old video, is fantastic, given that back then - and even today - probably 80% of youtube authors post unwatchable videos because they relied on the built-in microphone on their computer, or the built-in microphone on their video camera. An easy test for authors is - post a test video, and watch the video on a laptop with the audio set to half. If you can't hear your test video, the microphone you used to record your video is bunk. it's the difference between reaching the audience, and losing the audience. Thank you!

you should say acceleration instead of speed

Thank you sir, fantastic diagrams n clarifications.

A little late but thank you :)

great explanation thank you very much bruda

Thanks

What would happen if there was resistence added to it?

Thanks a lot, this video was very helpful!

Hei there. Thanks, great video. I'm trying to find somewhere else on the Internet that covers these ideas. It's there anywhere I could look?

thank youuuuuu i finally get it

I found the reason I was searching for

Hi Pete thanks a lot for this, Very helpful

great

Sir please tell me about newton 2nd law

man i love you so much

Thanks, but what I don't understand is: In reality, the towbar itself is also an object with a mass. The forces on the towbar itself appear to be balanced: tension acting equally in opposite directions. Yet the towbar is also accelerating at the same rate as the cab and the trailer, otherwise it wouldn't stay in place. Why is the towbar accelerating at all if the forces on it are balanced? I understand in the case of a weight hanging off the ceiling by a string, because there is no movement anywhere and all the forces are balanced everywhere, but not in the case where a cab, towbar and trailer are accelerating at the same rate. Can you explain?

Great demonstrations, you must be a great teacher showing your students stuff like this.

I'm here a litlle late but I think it behaves the way it does because the magnetic flux is concentrated in the edges of the poles

question: another formula to find critical angle is c=sin^-1(n2/n1) but didn't snell's law state that n2/n1 = n ????? could you explain the relationship between the 2 formulas?

Nice 🥰

according to faraday's law only a change in magnetic field will produce emf (voltage) but in your video it's constant magnetic field so why would it produce an emf?

So well explained thankyou - simple and easy to follow!

that will be 13000 and not 1300

Is the potential difference across the components negative, because they take energy away from the electrons? Also, after passing through the second component, why doesn't the current stop despite giving the components all its energy?

I have been wondering about this for over 50 years, since my doctor father told me that the steam burn on my hand was from "latent heat of vaporization"--a phrase that sounded intriguing but that I had no idea what it meant. I think I finally understand! Bonus: How the steam heated the milk in the latte I'm drinking while I watch this. :) Good, thorough, easy-to-follow explanation. Thank you!

THANK U

Wow
