A transformer has 230 volts applied to the primary and gives 4.6 V in the secondary. The secondary is connected to a load which draws a current of 5A. The current in the primary is

A

1A

B

0.1A

C

2A

D

10A

Text Solution

Verified by Experts

The correct Answer is:
C
`(I_p)/(I_s) = (V_s)/(V_p) :. I_(p) = 5 xx 4.6/230 :. I_(p) = 1/10 A`.
