# Properties of an electric transformer

The above is a schematic diagram of an electric transformer, where the primary AC voltage is $$220\text{ V}$$ and the secondary coil is connected with an electric heating instrument. The secondary voltage and current intensity are $$110\text{ V}$$ and $$8\text{ A},$$ respectively. Which of the following statements is correct?

There is no energy loss in this electric transformer.

$$a)$$ The current intensity flowing in the primary winding is $$4\text{ A}.$$
$$b)$$ The number of turns in the secondary winding is twice as many as that in the primary winding.
$$c)$$ The primary coil always transfers $$880\text{ W}$$ of electric power to the secondary coil without reference to any heating instrument.
