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

Text Solution

Verified by Experts

The amount of charge Q, that flows between two points at potential difference V (= 12 V) is 2 C. Thus, the amount of work W, done in moving the charge [from Eq. (12.2)] is
`W = VQ `
`= 12 V xx 2 C`
= 24 J.
