When will 1 C of charge pass a point in an electrical circuit?
Correct answer: C. When the current is 5mA for 200s
- A. When 1A moves through a voltage of 1V
- B. When a power of 1W is used for 1s
- C. When the current is 5mA for 200s
- D. When the current is 10A for 10s
Explanation
The formula used is Q = I x t Putting in the values, we get 1C as charge when Option C is used.

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.
