The primary winding of transformer has `500` turns whereas its secondary has `5000` turns. The primary is connected to an ac supply of `20V,50Hz`. The secondary will have an output of

A

200 V, 50 Hz

B

2 V, 50 Hz

C

200 V, 500 Hz

D

2 V, 5 Hz

Text Solution

Verified by Experts

The correct Answer is:
A
`N_(S)/N_(P)=V_(S)/V_(P)rArrV_(S)=5000/500xx20=200V`
and `f_(1)=f_(2)=50Hz`.
