If the voltage is 240V and the resistance is 60 ohms, the circuit current is ____ A.

Explanation:
Current in a circuit is found using Ohm's law: I = V / R. With 240 volts across 60 ohms, the current is 240 ÷ 60 = 4 amperes. So the circuit current is 4 A. For extra context, you can check power: P = VI = 240 × 4 = 960 W, which also equals I²R = (4)² × 60 = 960 W.
