Question

What happens to the flow of charges when the potential difference between two points becomes zero?

Answer 1

1. The potential difference between two points in a circuit is the amount of work done in moving a unit charge from one point to another.
2. The flow of charges is associated with the potential difference between two points in a conductor.
3. Charges can flow between two points in a conductor only if there is some potential difference between them.

Hence, when the potential difference between two points becomes zero the flow of charges stops or becomes zero.
