A step-up transformer has transformation ratio of `3:2` what is the voltage in secondary if voltage in primary is `30V`?

A

`45V`

B

`15V`

C

`90V`

D

`300V`

Text Solution

Verified by Experts

The correct Answer is:
A
`(V_(s))/(V_(p))=(N_(s))/(N_(P))=kimplies(V_(s))/(30)=(3)/(2)impliesV_(s)=45V`
