  1. Question 1

    Q1. A 10 V battery is connected to a 1 Ω resistor. If the current drawn is 2 A, what is the power dissipated?

    • A) 10 W
    • B) 15 W
    • C) 20 W
    • D) 25 W

    Answer: 20 W

    Explanation: Using the formula P = I^2R, we find the power dissipated. The other options are incorrect due to incorrect calculations or assumptions.
