Question

the number of turns in primary and secondary coils of a transformer are `100` and `20` respectively. If an alternating potential of `200` volt is applied to the primary, the induced potential in secondary will be
A. `10V`
B. `40V`
C. `1000V`
D. `20,000V`

Answer 1

Correct Answer - B
`(E_(S))/(E_(p))=(N_(p))/(N_(s))implies(200)/(E_(s))=(100)/(20)impliesE_(s)=40V`
