In a transformer the transformation ratio is 0.3. If 220 V ac is fed to the primary, then the voltage across the secondary is

In a transformer with transformation ratio 0.1, 220 volt a.c. is fed to primary. What voltage is obtained acorss 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 primary and secondary coil of transformer are 1000 to 5000 and 90 V ac is applied to primary, hence the voltage at the secondary 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 ........

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 .

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 :

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 :
