The number of turns in primary and secon...

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`

Text Solution

Verified by Experts

The correct Answer is:
B
`(E_(S))/(E_(p))=(N_(p))/(N_(s))implies(200)/(E_(s))=(100)/(20)impliesE_(s)=40V`
