Electric current may be defined as:
Correct answer: A. Rate of flow of charge
- A. Rate of flow of charge
- B. Rate of flow of momentum
- C. Rate of flow of power
- D. Rate of flow of energy
Explanation
Option A is correct. Electric current is defined as the rate of flow of electric charge through a conductor. It is measured in amperes (A) and is given by the equation: I = Q/t, where I is the current, Q is the charge flowing through the conductor, and t is the time.I=Q/t

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.
