A transformer has `100` turns in the primary coil and carries `8A` current. If input power is one kilowatt, the number of turns required in the secondary coil to have `500V` output will be

A transformer carries 8 A current in the primary of 100 turns. If the inpur power is 1kW, what should be the number of turns in the secondary to have a 500 V output?

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 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 :

In a transformer, number of turns in the primary coil are 140 and that in the secondry coil are 280. If current i primary coil is 4A, then that in the secondary coil is

A step down transformer convert a voltage of 2200 V into 220V in the transmission line. Number of turns in the primary coil is 5000. Efficiency of transformer is 90% and its output power is 8kW. Calculate (i) the number of turns in the secondary coil, (ii) input power.

In a transformer, number of turns in the primary coil are 140 and that in the secondry coil are 280. If current i primary ciol is 4A, then that in the secondary coil is

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 transformer consisiting of 300 turns in the primary and 150 turns in the secondary gives output power of 2.2 kw. If the current in the secondary coil is 10 A, then the input voltage and current in the primary coil are:
