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.

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

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 ?

The magnitude of emf across the secondary of a transformer does not depend upon.....(a)The amplitude of emf applied across the primary (b)The resistance of primary and secondary (c)The number of turns in primary (d)The number of turns in secondary

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?
