Power in AC||Transformer

Power, Resonant || Transformer

A step down transformer connected to an ac mains supply of 220V is made to operate at 11V, 44W lamp. Ignoring power losses in the transformer what is the current in primary circuit.

Which among the following, is not a cause for power loss in a transformer-

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 :

AC quality factor and transformer

A: The power output of a practical transformer is always smaller than the power input. R: A transformer works on the principle of mutual induction.

Why do we use a transformer in AC circuits?

The output power in step-up transformer used in practice is
