In a step-up transformer the turn ratio ...

In a step-up transformer the turn ratio is 1:10. A resistance of 200 ohm connected across the secondary is drawing a current of 0.5 A. What is the primary voltage and current?

A

50 V, 1 amp

B

10 V, 5 amp

C

25 V, 4 amp

D

20 V, 2 amp

Text Solution

Verified by Experts

The correct Answer is:
B
`V_(S)/V_(P)=N_(S)/N_(P)rArr(0.5xx200)/V_(P)=10/1rArrV_(P)=10V`
`i_(P)/i_(S)=N_(S)/N_(P)rArri_(P)=5A`.
