When `2` amperes current is passed through a tangent galvanometer, it gives a deflection of `30^(@)`. For `60^(@)` deflection, the current must be

When 2A current is passed through a tangent galvanometer, it gives a deflection of 30^@ . For 60^@ deflection, the current must be :

When sqrt(3) ampere current is passed in a tangent galvanometer, there is a deflection of 30^(@) in it. The deflection obtained when 3 amperes current is passed, is

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

When a current is passed in moving coil galvanometer, the coil gets deflected because,

When a current is passed in moving coil galvanometer, the coil gets deflected because,

When current is passed through a tangent galvanometer there is no deflection of the needle . If current is reversed , the rotates by 180^(@) . Then the plane of the coil will be .
