In a step up transformer, the input voltage is 300 V and the output voltage is 15 KV. Then the ratio of the number of turns in the primary to that in the secondary is

A

`1:20`

B

`1:30`

C

`1:40`

D

`1:50`

Text Solution

Verified by Experts

The correct Answer is:
D
`(N_p)/(N_s) = (E_p)/(E_s) = 300/15000 = 1/50`.
