A transformer connected to 220 volt line...

A transformer connected to `220` volt line shows an output of `2A` at `11000` volt. The efficiency is `100%`. The current drawn from from the line is

A

100A

B

200A

C

22A

D

11A

Text Solution

Verified by Experts

The correct Answer is:
A
`I_(P)V_(P)=I_(S)V_(S)`
`rArrI_(P)=(2xx11000)/220=100A`.
