In a T.G. experiment , for two different values of current , the deflections are `45^(@) " and " 30^(@)` respectively , then the ratio of the current is

A

`2:3`

B

`3:2`

C

`sqrt3:1`

D

`1:sqrt3`

Text Solution

Verified by Experts

`I_1=tan theta_1`
`I_2=tan theta_2`
`I_1/I_2=(tan 45^@)/(tan 30^@) =1/(1/sqrt3)=sqrt3/1`
