  1. Question 1

    Q1. A 12 V battery drives 2 A through a resistor. What power is dissipated?

    • A) 6 W
    • B) 14 W
    • C) 24 W
    • D) 0.17 W

    Answer: 24 W

    Explanation: Electrical power is calculated as P = V × I, where V is voltage and I is current. With a 12 V battery driving 2 A, the power dissipated is 12 × 2 = 24 W.
