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

A 66 % efficient transformer is working on 110 V and 2.2 kW power.If current in secondary coil is 6.0 A, calculate (i) current in primary coil and (ii) voltage across 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 6 A, the voltage across the secondary coil and the current in the primary coil respectively are
