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 `120V` and the current flowing in it is `10A`. The voltage and the current in the secondary are

A

240 V, 5A

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
`(e_(S))/(e_(P))=(n_(S))/(n_(P))`
`therefore e_(S)=(200)/(100)xx120=240V`
`I_(S)=(n_(P))/(n_(S))xxI_(P)=(100)/(200)xx10=5A`
