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 primary coil of an ideal transformer has 100 turns and the secondary coil has 600 turns. Then

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

The number of turns in the primary coil of a transformer are 100 and that in the secondary coil are 200. What type of transformer is it ? If the input voltage in the primary coil of the transformer is 200 V, find the output voltage in the secondary coil of the transformer.

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 transformer has turn ration 100//1 . If secondary coil has 4amp current then current in primary coil is

The number of turns in the primary coil of a transformer is 200 and the number of turns in the secondary coil is 1.0 if 240 volt AC is applied to the primary, the output from the secondary will be

The number of the turns in the primary coil of a transformer is 10 times than the same in the secondary coil . If the voltage across the primary is 20 V then find the voltage across the secondary .
