A power transmission line feeds input power at 2300 V to a step- down transformer with its primary windings having 4000 turns. What should be the number of turns in the secondary in order to get output power at 230 V?

A transformer is used to change the alternating voltage to a high or low value. A power transmission line feeds input power of 2300 V to a stepdown transformer with its primary windings having 4000 turns. What should be the number of turns in the secondary in order to get output power at 230 V?

A transformer working on a 240 V AC supplies 12V. The number of turns in the primary coil is 1000. Calculate the number of turns in the secondary coil.

When 240V was applied to the primary of a transformer, the voltage in the secondary was 12V. If the number of turns in the primary is 4,800 what will be the number of turns in the secondary2

A transformer working on a 240 V Acsupplies a voltage of 8 V to an electric bell in the circuit. The number of turns in the primary coil is 4800 . Calculate the number of turns in the secondary coil.

Arun decided to construct a transformer to change 240 V to 12 V. Find the number of turns in the primary if 200 turns are used in the secondary ?

There are 10000 turns in a trànsformer. Voltage in the primary is 0.2A. The transformer is wound so as to get a current 0.4A in the secondary. What is the maximum output power that received from this transformer?

A transformer without power loss carries 4000 turns in the primary and 2000 turns in thw secondary. If the primary voltage is 120 V and the current is 0.2 A . What is the maximum output power ?

Primary of a transformer has 20,000 turns and the secondary has 30,000 turns. 160V AC is applied at the primary ofthe transformer? lf the number of turns in the secondary transformer is greater than that in the primary then more voltage is induced in the secondary. Why?
