An ideal transformer has `100` turns in the primary and `250` turns in the secondary. The peak value of the ac is `28 V`. The r.m.s. secondary voltage is nearest to

A

`50 V`

B

`70 V`

C

`100 V`

D

`40 V`

Text Solution

Verified by Experts

The correct Answer is:
A
`(N_(s))/(N_(p))=(V_(s))/(V_(p))implies(250)/(100)=(V_(s))/(28//sqrt(2))impliesV_(s)=50V`
