A tangent galvanometer has a reduction factor of 1 A and it is placed with the plane of its coil perpendicular to the magnetic meridian. The deflection produced when a current of l A is passed through it is

A

`60^(@)`

B

`45^(@)`

C

`30^(@)`

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
b
In tangent galvanometer, I = K tane where K is reduction factor
`I = 1 A, K = 1 A`
`:.tantheta=1impliestheta=45^(@)`
