Question

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. `200V,50Hz`
B. `2V,50Hz`
C. `200V,500Hz`
D. `2V,5Hz`

Answer 1

Correct Answer - A
`(V_(s))/(V_(p))=(N_(s))/(N_(p))implies(V_(s))/(200)=(5000)/(500)impliesV_(s)=200V`
Frequency remains unchanged.
