When a current of 1A flows for 5 sec through the lamp. How much charge flows through the lamp
Correct answer: B. 5C
- A. 10C
- B. 5C
- C. 1C
- D. Insufficient data
Explanation
The charge (Q) flowing through a conductor is given by Q = I * t, where I is the current and t is the time.

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.
