Electric potential is defined as
Correct answer: A. work per unit charge
- A. work per unit charge
- B. force per unit charge
- C. power per unit charge
- D. force
Explanation
Electric potential is a measure of the electric potential energy per unit charge at a point in an electric field. It represents the amount of work done in bringing a unit positive charge from infinity to that point in the electric field.

About Current Electricity
Steady current relates charge flow to potential difference, resistance and resistivity, including how temperature changes a conductor's resistance. Sources with internal resistance have terminal voltage below their emf when delivering current, and maximum power output occurs under a specific load condition rather than at zero resistance.
