The SI unit of electric potential is

Question

Accepted Answer

C. {'text': 'joule per coulomb', 'label': 'C'}

1. Electric potential at a point = work done per unit positive charge to bring it from infinity to that point.
2. So units are J / C, which is named the volt (V).
3. (A) is the unit of electric field, (C) is field × distance, (D) is the reciprocal of potential.
