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

`5A`

B

`50A`

C

`500A`

D

`0.05A`

Text Solution

Verified by Experts

The correct Answer is:
D

`(V_(p))/(V_(s))=(i_(s))/(i-(p))implies(220)/(22000)=(i_(s))/(5)implies(i_(s)=0.05` amp
