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 moving coil galvanometer shows a deflection of 12^(@) , when a current of 1 mA flows through it . If the current is 2 mA , then the deflection 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 shows no deflection when a current is passed through it. But when the current is reversed, it gives a delfection of 180°, then the plane of the coil should have been oriented:.

In a moving coil galvanometer the current 'I' is related to the deflection theta as

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
