Question

How much work is done in moving a charge of 2 C across two points having a potential difference of 12 V?

Answer 1

The amount of charge, Q that flows between two points at a potential difference, V (= 12 V) is 2 C.
Therefore, the amount of work done, W in moving the charge is given by:

W = V × Q
= 12 V × 2 C
= 24 J
