  1. Question 1

    Q1. A step-up transformer has a turns ratio of 10:1. If the primary voltage is 220 V, what is the secondary voltage?

    • A) 2200 V
    • B) 220 V
    • C) 22 V
    • D) 22000 V

    Answer: 2200 V

    Explanation: Turns ratio = V_s/V_p; 10/1 = V_s/220, so V_s = 2200 V. Option B is incorrect as it's the primary voltage, not secondary.
