Question

Can anyone tell me what is a the work of galvanometer?​

Answer 1

Answer:

A galvanometer is an electromechanical instrument used for detecting and indicating an electric current. A galvanometer works as an actuator, by producing a rotary deflection of a pointer, in response to electric current flowing through a coil in a constant magnetic field. 

Answer 2

Answer:

A galvanometer is an electromechanical instrument used for detecting and indicating an electric current

Explanation:

Galvanometer, instrument for measuring a small electrical current or a function of the current by deflection of a moving coil. The deflection is a mechanical rotation derived from forces resulting from the current.
