Question

The ratio of the number of turns of the primary coil to the secondary coil of an ideal transformer is \( 5 : 1 \). The primary is connected to \( 220 \, V \) supply. What is the output power of the transformer if the output resistance is \( 11 \Omega \)?

• A. 1760 W
• B. 1100 W
• C. 176 W
• D. 100 W

Hint:

In an ideal transformer, power is conserved. First find secondary voltage using turns ratio, then apply Ohm’s law to get current and power.

Answer 1
