Galvanometer Types and Working Principle Quiz

A galvanometer is a device used to detect small electric current or measure its magnitude.

Some different types of galvanometers include Tangent galvanometer, Astatic galvanometer, Mirror galvanometer, and Ballistic galvanometer.

The main type of galvanometer used widely today is the D’Arsonval/Weston type or the moving coil type.

<p>A moving coil galvanometer is an instrument used to measure electric currents. It is a sensitive electromagnetic device which can measure low currents even of the order of a few microamperes.</p> Signup and view all the answers

<p>A current-carrying coil when placed in an external magnetic field experiences magnetic torque. The angle through which the coil is deflected due to the effect of the magnetic torque is proportional to the magnitude of current in the coil.</p> Signup and view all the answers
