List of top Physics Questions on Transformers asked in KEAM

In a transformer circuit it is possible to

A transformer operates at \(V_p=6\) kV on the primary side and supplies electric energy at \(V_s=220\) V to a number of houses in a town. If the total power consumption by the town is \(7.2\) kW, the current (in ampere) in the primary is

A transformer connected to 220 V mains is used to light a lamp of rating 100 W and 110 V. If the primary current is 0.5 A, the efficiency of the transformer is (approximately)

A step down transformer increases the input current 4 A to 24 A at the secondary. If the number of turns in the primary coil is 330, the number of turns in the secondary coil is

A step down transformer increases the input current 4 A to 24 A at the secondary. If the number of turns in the primary coil is 330, the number of turns in the secondary coil is
