Resistivity

[@kevinrt5294]

As a Neet aspirant... that's awesome way to explain the theory than teaching on blackoard which is done by most the Indian teachers. Thank :))

[@FlippingPhysics]

Best of luck on that NEET exam! And I am very glad you have found my videos!!

[@learningisecstatic9348]

Thank you sir. I m from India. Waking up in the morning and seeing a notification from you is starting the day in a happy mood.

[@FlippingPhysics]

I hope this morning is equally happy for you!

[@learningisecstatic9348]

@@FlippingPhysics yes sir. Thank you sir.

[@Luminate.tv.]

feel like liking this video all over again...very interesting. i have a better understanding of resistivity

[@aina5146]

sir your videos are awesome & i learn alot from your videos and i humbly request you to make videos on capacitor .

[@carultch]

His video on capacitors is coming up soon.

just saved my whole physics presentation.

Question one: how do electrons flow through the foil Are some electrons being moved all over the sheet? Or does it continue in some “imaginary line” through the foil?

[@harshithgowni1528]

I'm pretty sure that the power source gives a potential difference which entices the electrons to flow in a fixed direction depending on how the terminals of the power source are placed. The electrons are continuously moving (especially in conductors and superconductors) but they don't have any specific direction and hence cannot conduct electricity, without the power source of course. Am I right Mr.P?

Really hatts off

[@duckymomo7935]

Question two how do you not get shocked? Or is the current too insignificant?

[@carultch]

He's handling the alligator clips by the plastic covers, rather than the metal connectors. Even if he did touch the leads directly, the 1.5V source of the battery isn't enough to shock through a human body.

[@CruxCourse]

Please make one shot video for each chapter covering all concepts of a chapter in single video sirrrr

I enjoyed learning with you 🙂

'tis good

Hi sir, Why does a light bulb glow so fast when the drift velocity is very small, I mean what does it have to do with the electric filed, now I know that the field is so fast but the charges have to move fast for the light to come on when we turn on a light switch, right ? Thanks

[@carultch]

It's because there are trillions of electrons, in a path that is already filled with them. Consider this experiment with your water system for an analogy. Or simply consider it as a thought experiment, if not practical to try. First try turning on the faucet, and notice water instantly pours out. Now go to the main shutoff valve for your whole house, turn it off, and purge the existing water from your house's plumbing through the purge valve. After you purge the water, have a partner wait by the main shutoff valve, while you return to the kitchen sink. Turn on the faucet, and of course nothing comes out. Now call your partner on the phone, to tell them to turn on the main shutoff valve. You will notice that it takes time for the water to fill the pipelines, and get to the kitchen sink, when the water has to start at the main shutoff valve and the pipes aren't pre-filled. The former ALWAYS happens with electricity, and the latter never happens with electricity. This is because the conductors are already filled with electrons ready to conduct. Unlike the water supply, where you can purge the system and empty the pipes, you cannot empty a conductor of its pre-filled electrons. This is why, despite the low drift speeds, that electricity quickly supplies power to the loads..

The video was so good that I watched both the ads.

[@FlippingPhysics]

Thanks!

Can i really crack iit using these videos?🤔
