Question
The potential difference across points A and B in terms of Va and Vb is
- Vab = Va – Vb
- Vab = Vb – Va
- Vab = Va + Vb
- Vab = Va/Vb
Hint:
Vab=Va-Vb
The correct answer is: Vab = Va – Vb
- The potential difference across points A and B is Vab (point A is at a higher potential, point B is at a lower potential).
- And is written as, Vab= Va-Vb
- So, the correct option is a.
