Question

DEFINE potential differnce.give its units define it

Answer 1

The amount of work done(W) by bringing a unit positive charge(Q) from one point to another point is called Electric Potential Difference. Its SI unit is Voltage(V).

Answer 2

1)Potential Difference : Amount of work done per unit charge stored in a                                

                                                     conductor.

                                                            (or)

     Ensures constant or continuous flow of electrons from one point to    

                                                     another point.

2)Units of Potential Difference : Volts. Denoted by (V)

Volts=Work Done / Charge. Work Done is denoted by (W), and Charge is

                                            denoted by (Q)

So, V=W/Q.

Hope u got ur answer.
