Question

explain tangent galvanometer

Answer 1

 a galvanometer consisting of a very small magnetic needle in the center of a large vertical circular coil of wire through which electric current is passed and whose plane is in the magnetic meridian with the intensity of the current being proportional to thetangent of the angle of deflection of the needle.

Answer 2

A galvanometer consisting of a very small magnetic needle in the center of a large vertical circular coil of wire through which electric current is passed and whose plane is in the magnetic meridian with the intensity of the current being proportional to thetangent of the angle of deflection of the needle.

Tangent galvanometer is an early measuring instrument for small electric currents. It consists of a coil of insulated copper wire wound on a circular non-magnetic frame. Itsworking is based on the principle of the tangent law of magnetism.
