Question

Explain the working of galvanometer...​

Answer 1

$\huge\boxed{\fcolorbox{white}{pink}{AnsweR}}$

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

$\huge\underbrace{\orange{answer}}$❤️

A galvanometer is a device that is used to detect small electric current or measure its magnitude. The current and its intensity is usually indicated by a magnetic needle’s movement or that of a coil in a magnetic field that is an important part of a galvanometer.
