An a.c. voltage of 200 V is applied to the primary of a transformer and voltage of 2,000 V is obtained form the secondary. Calculate the ratio of the currents through the primary and secondary coils.

An a.c voltage of 300V applied to the primary of a transformer & voltage of 3000V is obtained from the secondary coil. Calculate the ratio of circuit in the primary & secondary coils.

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

In a transformer, the number of turns in primary coil and secondary coil are 5 and 4 respectively. If 240 V is applied on the primary coil, then the ratio of current in primary and secondary coil is

In a stepup transformer, the ratio of number of turns in primary and secondary coils is 1 : 10 . What voltage will develop in the secondary if the primary is connected to 220 V mains ? If the current drawn from the secondary is 2A, calculate the current through the primary

A transformer converts 200 V ac into 2000 V ac. Calculate the number of turns in the secondary if the primary has 10 turns.
