Question

1.a) What amount of work is needed in moving 15 C of charge through a

potential difference of 0.1 8 V?​

Answer 1

Given:

Charge = 15C

Potential Difference = 0.18V

Work Done = ?

Solution:

Potential Diffence = Work Done/Charge

V = W/Q

Therefore by Substituting the values of V and Q, we get

0.18V = W/15C

= W = 15 x 0.18

= W = 2.7J

Hence, the amount of Work Done is 2.7J
