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.

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

The number of turns in secondary coil of a transformer is 100 times the number of turns in primary coil. What is the transformer ratio ?

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 .

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

In a transformer, number of turns in the primary coil are 140 and that in the secondry coil are 280. If current i primary coil is 4A, then that in the secondary coil is

The input voltage and output voltage in the primary and secondary coils of a transformer are 250 V and 5 V, respectively. If the number of turns in the primary coil of the transformer is 1000, find the number of turns in its secondary coil. Also mention, whether the transformer is a step-up one or a step-down one ?

A setup transformer develops 440 V in secondary coil for an input of 200 V A.C Then the type of transformer is

The number of turns in the primary and secondary coils of a transformer are 100 and 300 respectively. If a 50 V, 50 Hz, a.c. supply is applied to the primary coil of the transformer, then the P.D. Per turn of the secondary will be

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
