Question

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?

Answer 1

Secondary voltage on second transformer is 200 volt.

Step-by-step explanation:

It is given two transformer

Let us consider first transformer.

Number of turns in primary
`N_p=300`

Numb er of turns in secondary
`N_s=500`

Now consider second transformer

Number of turns in primary
`N_p=250`

Number of turns in secondary
`N_s=1000`

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

For second transformer

`(N_p)/(N_s)=(V_p)/(V_s)`

`(250)/(1000)=(50)/(V_s)`

`V_s=200volt`

So secondary voltage on second transformer is 200 volt
