Charging by Conduction and Induction

[@rithvikyagnamurthy6560]

I honestly had a lot of trouble with this concept, however, rewinding multiple times, taking notes, and reading your lecture notes over and over again really helped! I honestly think it would be impossible for me to understand this without your explanation! Thank You!

Hi. Nice video. I have a question about charging the electroscope by induction. Shouldn’t the electrons flow from the ground to the electroscope because you are touching the side accumulated with positive charges and by coulomb law, the distance between your finger and positive charge is smaller than the distance between your finger and balloon, hence the force of attraction is greater than repulsion.

[@richasingh9613]

Nice explanation....thank you for providing this amazing video......

Disculpa amigo. De que material esta hecho ese corcho por donde se introduce el metal? He repetido ello con un matraz de pirex, un alambre de cobre y dos laminitas de aluminio, y cuando le acerco el globo, tambien un tubo de pvc practicamente las laminas no abren. Hay algun criterio en la eleccion del aislante entre el conductor metalico y el frasco de vidrio? Espero respuestas gracias.

[@M.SADKHAN]

[@niritzhak6158]

For induction, in the demonstration you did, would it be the same if the object was positive, and make the electroscope negative? Would this still cause the leaves to repel?

[@loganhagendoorn6327]

For induction, since there is a positive charge at the top of the electroscope and he touches the top of the electroscope, wouldn't he feed some electrons to the top of the electroscope, and then when he takes everything away, the electroscope is left with a net negative charge?

[@nowshad843]

from 12:04 , we see that the distance between metal foils starts to decrease before the finger even touches the ball, why does this happen?

[@M7medKasem]

10:00 when we grounded the electroscope, the electroscope didn't have any excess electrons to be transferred into the ground as charging via conduction Is just a change in the arrangement of protons and electrons in a matter. my question is, what exactly happened when we grounded the electroscope in this monment

[@oabdullae]

Indeed there's no excess electrons in the electroscope but the electrons in it are pushed away by the balloon (as the electric force is a force at distance) to the ground

[@maxostlind1148]

Hello rubber is an insulator. How is it able to transfer electrical charges to the metal sphere?

[@Raiden_Amani]

Thank you so much! Very helpful

[@FlippingPhysics]

You are very welcome

[@ashutoshbhakuni303]

Confusion: Induction method- The metal ball has more positive charge when finger is brought near it; so why dont electrons flow from finger to the metal ball by attraction of the positive charge on the ball? Electrons coming up from foil to go to finger/ground are being repelled by the balloon so it should be hard for them to flow to the finger… why in both cases electrons flow to the finger?

[@maxwang2562]

ur rite

[@oabdullae]

Electrons will prefer to go to ground instead of being crowded in the foils since they repel each other in such case

[@therealmd8995]

He reminds me of Leonard Hofstader from The Big Bang Theory.

[@user-tk9dz2kb4c]

I have a doubt why doesn't the negative charge on the balloon get neutralized when u hold it but the electroscope does when u touch the ball Pls reply awesome video love frm india

[@FlippingPhysics]

The rubber balloon is an insulator and the metal electroscope is a conductor.

[@merzaali367]

by indction if i touched without bolon .did electron move to ground

[@rohanr5150]

The induction picture in the lecture notes seems off...

[@4isfour]

I wonder, what would happen if the positively charged fur (1) came in contact with the electroscope and (2) came in the proximity of the electroscope wherein in both situations, the balloon is still present.

[@oabdullae]

The electroscope foils always repel when the object coming next to it is charged no matter what's the sign of this charge So in the case of the fur which is positively charged it will attract electrons to the top of the electroscope leaving the bottom with fewer electrons thus positively charged, then both foils will have the same positive charge and they'll repel as a result. Electroscope just tells if there's a charge or not but does not tell its sign (positive or negative) as it behaves the same way in both cases

[@aakashneet7992]

Sir, I have a doubt, please Reply.... When you rubbed the ballon , it got negatively charged....... BUT why did the Excess electrons did not flowed through your body and remained in the baloon🙄

[@FlippingPhysics]

It is because rubber is an insulator not a conductor. I discuss the differences in this video: www.flippingphysics.com/resistivity.html

[@oyipepsi6132]

Good question! I had the same one

[@qbrid]

TYSM THIS HELPS A LOT!!!

[@FlippingPhysics]

Glad it helped!

[@gaissina]

If we keep the balloon touched to the electroscope longer, will the negative charge from the balloon all transfer to the electroscope? In other words, сan the balloon have no excess negative charge after the interaction (theoretically)?

[@oabdullae]

No the electrons will distribute uniformly, there will always be more electrons in both as they will share that excess of electrons in a way they reach equilibrium which is both objects will have some of that excess, if the balloon became neutral this violates that the electrons try to reach an equilibrium as we observe in nature

[@numankashif6158]

Sir! can you tell me why when balloon is in your hand and your are grounded why balloon not immediately become neutral?

[@oabdullae]

The balloon is not a conductor, so when he charges the balloon from a side, charges(electrons) don't move from that side to his hand(i.e. ground) If the balloon was a conductor then he will use an insulating handle attached to the balloon to hold the it as he can't charge it if he holds it by his hand for the reason you mentioned in your question.

Please tell me where you got or how you made the electroscope!

It was purchased a long time ago. Do not know from where. It's called a "Flask Form Electroscope".

[@zabuza55]

Would it be possible to make the balloon neutrally charged once again?

[@oabdullae]

By touching the area that has been charged with hands to ground it to make it neutral again

sir, I​ have​ a​ little​ question​s. 1) Can​ insulator​ conduct​ charge​ to​ another​ objects​ upon​ touching??? if​ it​ can, how??? 2) Can​ insulator​ be​ charge​d​ by​ conduction??? if​ it​ can, how??? I​ try​ hard​ to​ find​ the​ answer but​ I​ can't​ find​ the​ exact answer. Sorry​ for​ my​ bad​ grammar​ T-T

[@suparawichitkangosol7225]

In​ my​ class, teacher​ say​ that​ if​ you​ attach​ the​ insolator that​ have​ charge​ to​ metal ball (conductor), nothing will​ happen.​ So, it​ make​ me​ very​ confuse​d.#​ this is​ about​ question​ 1

[@suparawichitkangosol7225]

The​ another​ question, can​ insulator​ that​ has​ charge​​ be​ ground??? if​ it​ can, how???

[@oabdullae]

Apparently if you touch an insulator that is charged with a conductor, the electrons flow from the insulator to the conductor as there are too many of them on the insulator The insulator prevents electrons to flow to another insulator and not to another conductor. That's what I know, there may be some better explanation

[@mohammadhashemi1771]

is it possible to permanently give a metal surface a negative charge

[@oabdullae]

Definitely if you charged a metal surface negatively it'll stay negatively charged unless an external factor changes this state

[@mohammadhashemi1771]

@oabdullae I know this the question is how to do it?

[@oabdullae]

@@mohammadhashemi1771 If you kept the charged metal away any other charges then it will stay as it is, practically maybe you can't hold this forever all the way to infinity, but the idea is that it's possible to hold the charge of an object as long as we want by not letting it interact with other charges from outside

[@mohammadhashemi1771]

@oabdullae my setup requires and electrical current to pass through the metal at all time but the metal has to maintain the negative surface charge all the time

[@oabdullae]

@@mohammadhashemi1771 Maybe you can cover the metal with an insulating layer to prevent it from losing its charge

[@mariamelsawy6871]

what does the term ground mean in the video

[@prasantpanda5680]

It means the actual ground on which we stand. When we touch a charged body to ground, our body acts as bridge between the two and electrons are exchanged between ground and body, that balances out the charge and makes the body neutral. Here, the ground doesn't get charged because it's so vast and the very little number of electrons exchanged causes no net change in the charge of ground

[@Greg_Chase]

A pith ball is an insulator; and a wall is an insulator. If I rub a rubber rod with fur to make it negatively charged and touch the pith ball insulator, there is repulsion and the pith ball creates a physical distance to 'get away' from the rod - see time 1:40 here -> kzbin.info/www/bejne/pZvGl31tl8aUaJY If I rub a balloon with fur to make it negatively charged and touch it to the wall insulator, unlike the repulsion in the case above, the balloon is attracted and sticks to the insulator - the wall. See time 0:36 here -> kzbin.info/www/bejne/mJu4Xn-ia7pkn8k At first I thought "balloon attracts (sticks to) the insulator because the wall has a large volume for repelled electrons to move away from the negative charge on the balloon" and "the pith ball repels the insulator rubber rod because the pith ball is a small volume and its electrons cannot 'get away' from the electrons on the rod" THEN I recognized "wait a minute - the wall is not a conductor - there are no conduction band electrons - in an insulator, charge stays in one place and cannot freely move as it otherwise could in a conductor" So I'm a bit stumped. The atoms become polarized in an insulator when a negatively-charged object is brought near (negative rod, negative balloon) - just like the dielectric in a capacitor. So the insulator wall attracts the negative balloon, but the insulator pith ball repels the negative rod. Sort of puzzling.
