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

A

15 V

B

45 V

C

300 V

D

90 V

Text Solution

Verified by Experts

The correct Answer is:
B
As, `(V_(S))/(V_(P))=(N_(S))/(N_(P))`
`rArr (V_(S))/(30)=(3)/(2)`
`rArr V_(S)=(30 xx 3)/(2)`
`rArr V_(S)=45V`
