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 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 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 220 V input is supplied to a transformer. The output circuit draws a current of 2.0 A at 440 V . If the efficiency of the transformer is 80% , the current drawn by the primery winding of the transformer is

A 220 V input is supplied to a transformer. The output circuit draws a current of 2.0 A at 440 V. If the efficiency of the transformer is 80%, the current drawn by the primery winding of the transformer is

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
