I was studying the chapter electric current and came up with a doubt in my mind . Basically when we pass electric field through a conductor then as the dielectric strength of a conductor is very high so it will be as following-
The electrons inside the conductor will move in presence of the field untill the density of the opposite charges becomes enough to oppose the external field provided by us .
- So net electric field in a conductor is always zero
Then I thought that it may possible that when we connect a battery in a circuit then due to the electric field produced by the battery the electrons inside the conductors of the circuit starts flowing And instead of accumulating at one place as that of the previous one it goes on moving inside the loop so here it's seen that inside the conductor the electric field is not zero . That when a conductor is bend in the form of a loop and used in a circuit with a battery then the electric inside it is non zero. Then why does we assign the same potential between any two points inside a conductor in a circuit though we know that in any electric field potential is different at different points
