The deflections produced by a Tangent Galvanometer at two different places when the same current is passed through it are and respectively. The ratio of the values of at two places is
The certain amount of current when flowing in a properly set tangent galvanometer, produces a deflection of If the current is reduced by a factor of the deflection would
A tangent galvanometer has turns of wire. The internal and external diameters of the coil are and respectively. The reduction factor of the galvanometer at a place where oersted will be ( oersted )
