Question

Which of the following statements is true?


1. Charge flows from a higher to a lower potential between the two points.
2. Charge always flows from a lower to a higher potential between the two points.
3. Current flows only when there is no potential difference between the two points.
4. Charge is always carried by the electrons.

Answer 1

i think it is no.2

Answer 2

How?

Answer 3

it is no.2 conventional current flows from high potential to lower potential , hence charge carriers (electrons ) move in opposite to current direction
