    • D.

      220 lilitan

    • E.

      300 lilitan

    Correct Answer
    B. 200 lilitan
    Explanation
    The number of turns in the secondary coil of a step-down transformer can be determined using the formula:
    (Ns/Np) = (Vs/Vp)
    Where Ns is the number of turns in the secondary coil, Np is the number of turns in the primary coil, Vs is the voltage of the secondary coil, and Vp is the voltage of the primary coil.
    In this case, the voltage ratio is (220/2200) = 1/10.
    Since the primary coil has 2000 turns, the number of turns in the secondary coil can be calculated as:
    Ns = Np x (Vs/Vp) = 2000 x (1/10) = 200 turns.
    Therefore, the correct answer is 200 turns.

    • D.

      25 A

    • E.

      30 A

    Correct Answer
    B. 15 A
    Explanation
    The power output of the transformer is given as 30 KW, and the input voltage is given as 2000 volts. To find the current through the primary coil, we can use the formula: power = voltage x current. Rearranging the formula to solve for current, we have: current = power / voltage. Substituting the given values, we get: current = 30,000 / 2000 = 15 A. Therefore, the correct answer is 15 A.
