Question

A current of 0.5 amperes flows through the filament of an electric bulb for 12 min. Calculate the amount of electric charge that flows through the circuit.
1. 360 C
2. 60 C
3. 36 C
4. 6 C

Answer 1

Correct Answer - Option 1 : 360 C

The correct answer is 360 C.

Given: 

Current (I) = 0.5 Amp

Time (t) = 12 min = 12 × 60 = 720 Sec

Formula:

Charge = Current × time

Q = I × t

Calculation:

Q = I × t

⇒ 0.5 x 720

⇒ 360 C.

Hence, the amount of electric charge that flows through the circuit is 360 C.
