  1. Question 1

    Q1. The turns ratio of a transformer is 2:1. If the primary voltage is 440 V, what is the secondary voltage?

    • A) 110 V
    • B) 220 V
    • C) 440 V
    • D) 880 V

    Answer: 220 V

    Explanation: V_secondary = V_primary * (N_secondary / N_primary) = 440 V * (1/2) = 220 V. Option A is incorrect because it is half the correct value.
