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

A current of 2A is flowing at 220 V in the primary coil of a transformer. If current in the secondary coil is 1 A and efficiency of the transformer is 80% then the voltage produced in the secondary coil will be

In an ideal transformer, the voltagae and the current in the primary coil are 200V and 2 A, respectively. If the voltage in the secondary coil is 200 V, then the value of current in the secondary coil will be

In a lossless transformer an alternating current of 2 amp is flowing in the primary coil. The number of turns in the primary and secondary coils are 100 and 20 respectively. The value of the current in the secondary coil is

A generator supplies 100 V to the primary - coil of a transformer of 50 turns.If the secondary coil has 500 turns, then the secondary voltage is

The number of turns in primary and secondary coils of a transformer is 50 and 200, respectively. If the current in the primary coil is 4 A, then current in the secondary coil is

A transformer has 1500 turns in the primary coil and 1125 turns in the secondary coil. If a voltage of 200V is applied across the primary coil , then the voltage in the secondary coil is :
