A transformer has turns ratio `N_(s)/N_(p)=4` .If a 200V AC voltage is applied across its primary and it carries 1A current.Current in circuit connected to secondary coil if transformer is 80% efficient is

A transformer of efficiency 90% has turns ratio 10 : 1. If the voltage across the primary is 220 V and current in the primary is 0.5 A, then the current in secondary is

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

A transformer has 200 turns in primary coil and 600 turns in secondary coil. If a 220 V DC is applied across primary coil what will be the voltage across secondary coil.

A transformer has 250 primary turns and 500 secondary turns. If 200 V electric potential is applied to the primary resulting in a current of 5 mA, find the secondary voltage and current.
