A current of 1.0 A is drawn by a filament of an electric bulb for 10 minutes. The amount of electric charge that flows through the circuit is
- A.0.1 C
- B.10 C
- C.600 C
- D.800 C
Show answer
Charge equals current multiplied by time, and 1.0 A for 600 seconds gives 600 coulombs. Electric current is the rate of flow of charge, so I = Q ÷ t, or Q = I × t. Time must be in seconds: 10 minutes is 10 × 60 = 600 seconds.
