Question

find the work done in moving a charge of 4 c across the poetional diffence of 18 v

Answer 1

Work done in moving a charge is given by :

1/2CV²

Where :

C = Charge

V = Voltage

In our case :

C = 4

V = 18

Doing the substitution we have :

Work = 1/2 × 4 × 18²

= 2 × 324 = 648

= 648 Joules
