In a tangent galvanometer a deflection of `30^(@)` is obtained wth a certain current flowing through the coil. If the current is tripled, the deflection obtained will be

A tangent galvanometer propertly adjusted gives a deflection of 30^(@) when a certain current is passed through it. When the current is changed, then it gives a deflection of 45^(@) . The ratio of the currents in the two cases is

A tangent galvanometer gives a deflection of 30^(@) whewn a current of 250 mA is passed through its coil. If the radius of the coil is 8 cm and B_(H)=2.5xx10^(-5)Wbm^(-2) . Find the length of the wire used in winding the coil.

In a propertly adjusted tangent galvanometer, the deflection for 1A current is found to 30^(@) . Now the coil is turned through 90^(@) about the vertical axis, the deflection for the same current will be

Tangent galvanometer shows a deflection of 45^@ for some current. When the current is reduced to 1//sqrt(3) times the original , what is the deflection ?
