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

Text Solution

Verified by Experts

The amount of chrge Q, that flows between two potnts at potential difference V(=12V) is 2 C. Thus, the amount of work W, done in moving the charge [frim Eq. (12.2)] is
W = VQ
`= 12V xx 2C`
=234 J.
