A current of `((2)/(sqrt(3)))` A produces a deflection of `60^(@)` in a tangent galvanometer.The reduction factor is

A

`((2)/(sqrt(3)))`A

B

`((2)/(3))`A

C

2A

D

`((3)/(2))A`

Text Solution

Verified by Experts

The correct Answer is:
B
For tangent galvanometer
`I=Ktantheta`
Where K Is the reduction factor of tangent galvanometer.
or `K=(I)/(tantheta)=((2)/(sqrt(3)A))/(tan60^(@))=((2)/sqrt(3))/(sqrt(3))=(2)/(3)A`
