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. None of them
Explanation
Electric current may be defined as the rate of flow of charge. Electric current is the measure of the flow of electric charge through a conductor per unit of time. It is typically measured in units of amperes (A), where 1 ampere is equal to 1 coulomb of charge passing through a conductor in 1 second. So, the correct definition is "Rate of flow of charge."

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.
