  1. Question 1

    Q1. A transformer has 100 turns in the primary coil and 500 turns in the secondary coil. If the primary voltage is 220 V, what is the secondary voltage?

    • A) 440 V
    • B) 880 V
    • C) 1100 V
    • D) 2200 V

    Answer: 1100 V

    Explanation: V_secondary = V_primary * (N_secondary / N_primary) = 220 V * (500 / 100) = 1100 V. Option A is incorrect because it is less than the correct value.
