The voltage across the primary winding is 6000 V. If the primary winding has 50 coils and the secondary winding has 20 coils, what is the secondary voltage?

For an ideal transformer, the voltage ratio equals the turns ratio: secondary voltage ÷ primary voltage = secondary turns ÷ primary turns. So the secondary voltage is 6000 × (20 ÷ 50) = 2400 V. The correct choice is 2400 V.
