Q-- define potential difference?

Answer 1

Q-- define potential difference?
Ans ---- 1)the potential differnce between two points ina electric circuit is defined as the amount of workdone in a moving a unit of charge from one points to other point.


POTENTIAL DIFFERENCE = WORK DONE /QUALITY OF CHARGE MOVED
V=W/Q
2)SI unit of potentail difference is volt.

Answer 2

THE AMOUNT OF WORK DONE IN MOVING A CHARGE FROM ONE POINT TO ANOTHER IS CALLED AS POTENTIAL DIFFERENCE
V=W/Q.
