In a transformer, the number of truns in the primary and the secondary are 410 and 1230 respctively. If the current in primary is 6A, then that in the secondary coil is:

A

2A

B

18A

C

12A

D

1A

Text Solution

Verified by Experts

The correct Answer is:
A
For a transfer
`V_(s)/V_(p)=N_(s)/N_(p)=I_(p)/I_(s)`
`N_(p)=410 , N_(s)=1230`
` I_(p)=6AI_(s)?`
` N_(s)/N_(p)=I_(p)/I_(s)`
`1230/410=6/I_(s)`
`3=6/I_(s)`
`thereforeI_(s)=6/3=2A`
