In transformer , power of secondary coil is :

An ideal transformer has primary and secondary coils of 200 turn and 40 turns respectively. If the current in the primary coil is 3A. Then the value of current in the secondary coil wil be

Transformer is a device used to increase or decrease the voltage in the transmission line according to requirement, Generally the input line voltage is fed in a primary coil and the output line voltage is obtained from the terminals of another coil In an ideal transformer, the primary and secondary coils are linked is such a way that there is no loss of magnetic flux and electrical energy. In an ideal transformer, if the number of turns and input voltage across the terminals of the primary coils be N_1 and V_1 , then the output voltage at the two terminals of the secondary coil V_2=V_1.N_2/N_1 , where N_2 is the number of turns in the secondary coil . In question (i) if the input power of the transformer be 44 W, then output power is

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

When power is drawn form the secondary coil of a transformer, the dynamic resistance.

A transformer having efficiency 90% is working on 100 V and at 2.0 kW power. If the current in the secondary coil is 5A, calculate (i) the current in the primary coil and (ii) voltage across the secondary coil.

A transformer having efficiency of 90% is working on 200 V and 3 kW power supply. If the current in the secondary coil is 6A , the voltage across the secondary coil and current in the primary coil respectively are
