Question

define potential difference

​

Answer 1

work done for moving a charge from infinite to a point to another point .

OR

difference of two potential is called potential difference

Answer 2

Answer:

Electric potential is the work done per unit charge in bringing the charge from infinity to that point against electrostatic force. In a conductor, electrons flow only when there is a difference in electric pressure at its ends. This is also called potential difference.
