A current of 5 A exists in a 10 Ω resistance for 4 minutes. The charges that pass through any cross-section of the resistor in this time equals __ C.
Charge = It = 5 × (4 × 60) = 1200 C
A current of 5 A flows through a circuit for 15 minutes. The amount of electric charge that flows through the circuit during this time equals __ C.
