The number of turns in secondary coil of a transformer is 100 times the number of turns in primary coil. What is the transformer ratio ?

In the secondary coil of step-up transformer , the number of turns are ___

The number of turns in the primary coil of a transformer is 200 and the number of turns in the secondary coil is 1.0 if 240 volt AC is applied to the primary, the output from the secondary will be

The number of turns in the secondary coil of a transformer is 20 times that in primary. What value of power will be obtained in secondary, if power fed to primary is 100 watt ?

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 input voltage and output voltage in the primary and secondary coils of a transformer are 250 V and 5 V, respectively. If the number of turns in the primary coil of the transformer is 1000, find the number of turns in its secondary coil. Also mention, whether the transformer is a step-up one or a step-down one ?

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 ratio of number of turns in primary and secondary coil of a transformer is 1:20 the ratio of current in primary and secondary coils will be ....
