  1. Question 1

    Q1. A lamp uses 60 W at 120 V steady. What current does it draw?

    • A) 0.50 A
    • B) 2.0 A
    • C) 7.2 A
    • D) 60 A

    Answer: 0.50 A

    Explanation: Current is calculated using I = P/V, where P is power in watts and V is voltage. For a 60 W lamp at 120 V, the current is 60 ÷ 120 = 0.50 A.
