| Dec 20, 2021 at 11:13 | comment | added | Jivan Pal | @PredakingAskboss At 13:35 in this video, there is a visual demonstration of what I'm talking about: the battery simply provides electromotive force to move electrons form +ve terminal to –ve terminal, whence the electrostatic force (or equivalently, the electric field that results from the new arrangement of the electrons) causes the electrons in the wire to move. The battery has no direct influence over what happens in the wire; only influence over what happens within it and immediately outside of it. | |

| May 27, 2021 at 18:48 | comment | added | Predaking Askboss | you said that batteries don't do the work to move electrons in the rest circuit. So according to you what is doing it. Any energy coming from any other thing. That's really silly to say that batteries don't do work on electrons on rest circuit | |
| May 27, 2021 at 18:34 | comment | added | Jivan Pal | Consider a specific electron. Regardless of which battery it moves through, it will end up in the same position on the other side of the two batteries, so the resulting electric field is the same. | |
| May 27, 2021 at 18:34 | comment | added | Jivan Pal | There seems to be some confusion on your end as to what situations the batteries are doing work in, so to clarify: a battery only does work to move electrons from its positive terminal to its negative terminal through the battery. It does not do work to move electrons through the rest of the circuit. That happens by virtue of the electric field produced by the arrangement of charges that results from the battery moving charges between its terminals. In other words, it results from the potential difference created by the battery. | |
| May 27, 2021 at 18:33 | comment | added | Predaking Askboss | What do you think terminals are actually doing? They are not shooting electrons throughout the circuit! When the electrons comes out of terminal and enters the resistor it is can be seen easily that electron is now in effect of both A and B. If you think only one of them is working then there will occur a flow of charge from one (+) terminal to another (+) terminal. Which js the not the case with same volt batteries. How will you confirm which terminal is actually doing the work? | |
| May 27, 2021 at 18:27 | comment | added | Jivan Pal | "NO! THIS DOESN'T MAKE SENSE. You will have both the batteries doing work together." — How do you come to this conclusion? If an electron is in battery A, and therefore being moved by the electromotive force produced by the chemical reaction occurring in battery A, how can the chemical reaction in battery B possibly affect it? | |
| May 27, 2021 at 18:08 | comment | added | Predaking Askboss | In your answer you said that only one battery is doing the work then how will you tell which battery is actually doing the work. NO! THIS DOESN'T MAKE SENSE. You will have both the batteries doing work together. You were very close to the answer which i think can be correct which is by eliminating something which makes both of them to be able to do work at the same time. | |
| May 27, 2021 at 17:34 | comment | added | Jivan Pal | "Batteries don't know what they are doing!" — I am not sure how you got the impression that they do somehow know what they are doing from my answer. I specifically did not anthropomorphise them. | |
| May 27, 2021 at 17:31 | comment | added | Jivan Pal | ... done by the battery on the charges in the first place (potential energy originally gained). | |
| May 27, 2021 at 17:31 | comment | added | Jivan Pal | "What do you think why electrons move? Then again, What is applying force on electrons near terminal and also to those electrons which are at long distance from terminals?" — They move due to the electric field which results from the potential difference created by the battery doing work on charges. (The electric field is the gradient of the electric potential field.) Conservation of energy tells us that there must be an electric field in the conductor such that the work done (potential energy expended/lost) by an electric charge moving through the conductor is equal to the work ... | |
| May 27, 2021 at 17:27 | comment | added | Jivan Pal | "chemical reaction produces charges that gets accumulated in terminal." — No, the chemical reaction in the battery moves already existing charges from one terminal to the other, thereby doing work on the charges, which increases their potential energy, thereby resulting in a potential difference across the battery. No charges are "produced". | |
| May 27, 2021 at 14:51 | comment | added | Predaking Askboss | you are giving none of the explanation asked here. Batteries don't know what they are doing! chemical reaction produces charges that gets accumulated in terminal. This is where the story begins. We have some charge accumulated on terminals that will like to get discharged because of potential differences. GOOD but nothing in this text that solves the query. Okay let me ask in a different way! What do you think why electrons move? Then again, What is applying force on electrons near terminal and also to those electrons which are at long distance from terminals?and How? | |
