A current of 0.5 A prioduces a deflection of `45^(@)` in a tangent galvanometre. What current will produce a deflection of `30^(@)` in the same tangent galvanometer.

A current of 10 A produces a deflection of 45^(@) in a tangent galvanometer. What is the value of the current which will produce a deflection of 30^(@) in the same galvanometer?

A current or 0.5 A produces a deflection of 60° in a tangent galvanometer. The cunent that produces a deflection of 30° in the same galvanometer is

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

A current of 4A produces a deflection of 30° in the galvanometer. The figure of merit is

If in a moving coil galvanometer, a current I produces a deflection theta , then

If in a moving coil galvanometer, a current I produces a deflection theta , then
