What is meant by 5 A?
Correct answer: A. A charge of 5 C flows through a point in 1 second
- A. A charge of 5 C flows through a point in 1 second
- B. 5V electricity is causing 1 C af charge to flow
- C. 5 V electricity flows across 1 Ω of resistance
- D. A charge of 5 C flows through a point in 5 seconds
Explanation
A is correct. Current= q/t. so 5A means 5C flowing in one sec from a point.

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.
