The efficiency of a transformer is 98%. The primary voltage and current are`200 V` and `6A`. If the secondary voltage is `100 V`, the secondary current

A

`11.76 A`

B

`12.25 A`

C

`3.06 A`

D

`2.94 A`

Text Solution

Verified by Experts

The correct Answer is:
3
`eta = (V_(s) I_(s))/(V_(p) I_(p)) implies (98)/(1000) = (100 xx i)/(200 xx 6)`
