In a step-up transformer the voltage in ...

In a step-up transformer the voltage in the primary is `220 V` and the currrent is `5A`. The secondary voltage is found to be `22000V`. The current in the secondary (neglect losses)is

A

`5 A`

B

`50 A`

C

`500 A`

D

`0.05 A`

Text Solution

Verified by Experts

The correct Answer is:
D
`I_(1)E_(1)=I_(2)E_(2) rArr I_(2)=(I_(1)E_(1))/E_(2)=(5xx220)/22000=.05A`
