Question
How much work is done in moving a charge of $2 \ C$ across two points having a potential difference $12 \ V?$
✓
Answer
- Solution: 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 is
- $W=V Q$
- $=12 \ V \times 2 C$
- $=24 \ J$
