The primary winding of a transformer has 100 turns and its secondary winding has 200 turns. The primary is connected to an ac supply of 120 V and the current flowing in it is 10 A. The voltage and the current in the secondary are

A

240 V, 5 A

B

240 V, 10 A

C

60 V, 20 A

D

120 V, 20 A

Text Solution

Verified by Experts

The correct Answer is:
A
`V_(S)/V_(P)=N_(S)/N_(P)rArrV_(S)/120=2000/100rArrV_(S)=240` Volt
`N_(S)/N_(P)=I_(P)/I_(S)rArrI_(S)=10/2=5A`.
