In a primary coil 5A current is flowing ...

In a primary coil `5A` current is flowing on `220` volts. In the secondary coil `2200V` voltage produces. Then ratio of number of turns in secondary coil and primary coil will be

A

`1:10`

B

`10:1`

C

`1:1`

D

`11:1`

Text Solution

Verified by Experts

The correct Answer is:
B
`(N_(s))/(N_(p))=(V_(s))/(v_(p))=(2200)/(220)=(10)/(1)`
