  1. Question 1

    Q1. In Kirchhoff's voltage law, what is the sum of voltage changes around a closed loop?

    • A) Always positive
    • B) Always negative
    • C) Zero
    • D) Depends on the circuit

    Answer: Zero

    Explanation: Kirchhoff's voltage law states that the sum of voltage changes around a loop is zero. Option A is incorrect as it doesn't account for voltage drops.
