A battery of 12 V is connected to primary of a transformer with turns `n_(s) // n_(P) = 10`. Voltage across secondary would be

In a step up transformer, the turn ratio is 3 : 2. A battery of EMF 4.5V is connected across the primary windings of transformer. The voltage developed in the secondary would be:

The primary and the secondary coils of a transformer contain 10 and 100 turns, respectively. The primary coil is connected to a battery that supplies a constant voltage of 1.5 volts. the voltage across the secondary coil is

The ratio of primary and secondary turns in a transformer is 3:2, if 30V a.c. is fed to primary, voltage across secondary will be ........

A transformer has 200 windings in the primary and 400 windings in the secondary. The primary is connected to an a.c. supply of 110 V and a current of 10 A flows in it The voltage across the secondary and the current in its respectively are

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 ratio of primary and secondary turns in a transformer is 1: 200. If 220 V A.C. is fed to primary, voltage across secondary 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.
