Primary winding and secondary winding of a transformer has 100 and 300 turns respectively . If its input power is 60 W then outut power of the transformer will be :

The number of turns in the primary and secondary coils of a transformer are 100 and 300 respectively. If a 50 V, 50 Hz, a.c. supply is applied to the primary coil of the transformer, then the P.D. Per turn of the secondary will be

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 ?

Primary coil of a transformer is connected to "220V" ac.Primary and secondary turns of the transforms are "100" and "10" respectively.Secondary coil of transformer is connected to two series resistances shown in figure.The output voltage (V_(0)) is :

In an ideal transformer the number of turns of primary and secondary coils given as 100 and 300 respectively. If the power input is 60 W, the. power output is.

The primary coil of an ideal transformer has 100 turns and the secondary coil has 600 turns. Then

If primary winding of a transformer were connected to a battery , the current in it will :

A step down transformer converts transmission line voltage from 11000 V to 220 V. The primary of the transformer has 6000 turns and efficiency of the transformer is 60%. If the output power is 9 kW, then the input power will be

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 ?
