The transformer ratio of transformer is 10 : 1 . If the primary voltage is 440 V , secondary emf is

The efficiency of a transformer is 98%. The primary voltage and current are 200 V and 6A . If the secondary voltage is 100 V , the secondary current

The number of turns in the primary coil of a transformer are 100 and that in the secondary coil are 200. What type of transformer is it ? If the input voltage in the primary coil of the transformer is 200 V, find the output voltage in the secondary coil of the transformer.

The number of turns in primary and secondary coil of a transformer is 100 and1000. If the input voltage is (500V, 50Hz) then the output voltage will be:

A transformer has 300 primary turns and 2400 secondary turns: If the primary supply voltage is 230 V, what is the secondary voltage ?

In an ideal transformer , the primary and the secondary voltages always have

The number of the turns in the primary coil of a transformer is 10 times than the same in the secondary coil . If the voltage across the primary is 20 V then find the voltage across the secondary .

The transformer ratio of the step down transformer is 2 : 5 . Alternating voltage of 180 V amplitude is supplied to the primary. Calculate the r.m.s. value of secondary voltage
