The ratio of secondary and primary turns...

The ratio of secondary and primary turns of step-up transformer is 4 : 1.If a current of 4A is applied to the primary , the induced current in secondary will be

A

`8 A`

B

`2 A`

C

`1 A`

D

`0.5 A`

Text Solution

Verified by Experts

The correct Answer is:
C
`(I_s)/(I_p) = (N_p)/(N_s) = 1/4`
`I_s = 1/4 xx 4 = 1A`
