Consider two transformers. Transformer A has 300 turns on its primary and 500 turns on its secondary. Transformer B has 250 turns on its primary and 1000 turns on its secondary. The same voltage is supplied at the primary of both transformers. The secondary voltage in transformer A has an amplitude V = 50 V. What is the amplitude of the secondary voltage on transformer B?

Secondary voltage on second transformer is 200 volt.

Explanation:

It is given two transformer

Let us consider first transformer.

Number of turns in primary

Numb er of turns in secondary

Now consider second transformer

Number of turns in primary

Number of turns in secondary

Now it is given that same voltage of 50 volt is applied to primary of both the transformer.

For second transformer

So secondary voltage on second transformer is 200 volt

your answer is c! hope this : )
