Question

The primary resistance of a 440/110-V transformer is 0.5 Ω and the

secondary resistance is 0.04 Ω. When 440 V is applied to the primary and

secondary is left open-circuited, 200 W is drawn from the supply. Find the

secondary current which will give maximum efficiency and calculate this

efficiency for a load having unity power factor.
