In an ideal transformer, an output of 66 kV is required when an input voltage of 200 V is available. If the primary has 300 turns, how many turns should the secondary have ?

In an ideal transformer, an output of 66 kV is required when an input voltage of 220 V is available. If the primary has 300 turns, how many turns should the secondary have ?

A transformer is used to step up an alternating emf of 200V to 440V. If the primary coil has 1000 turns, calculate the number of turns in the secondary coil.

A step - up transformer is used on 120 V line to provide a potential difference of 2400 V . If the number of turns in the primary is 75, then the number of turns in the secondary shall be

An ideal transformer converts 220 V AC to 3.3 kV AC to transmit a power of 4.4 kW. If primary coil has 600 turns, then alternating current in 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 :
