A current of 5 A is flowing at 220 V in the primary coil of transformer. If the voltage produced in the secondary coil is 2200 V and 50% of power is lost, then the current in secondary will be

Answer: (C)

Solution

Input power in the primary is W. Since 50% of the power is lost, the output power is W. Then the secondary current is $ =
