Question

How do you define electric potential?

1. Qualitative definition.
2. Quantitative definition.

Answer 1

1. Qualitative definition of electric potential- Potential may be defined as the electrical property which determines the direction of flow of charge between two points. Charge flows from a point at a higher potential to that at a lower potential.
2. Quantitative definition of electric potential- Electric potential at any point is defined as the work done in bringing a unit positive charge from infinity to that point.
3. $electricpotential=\frac{workdone}{charge}$
4. The unit of electric potential is volt (V).
5. $1V=\frac{1joule}{1coulomb}$
