Write a short note on galvanometer.

Explanation

(i). Galvanometer is a sensitive device which works on the principle that a current carrying conductor placed in a magnetic field experiences a force.
(ii.) The pointer on the galvanometer dial is connected to a coil.
(iii.) The coil is placed between the pole pieces of a magnet such that, when small current flows through the coil, the rotation of the coil will be proportional to the current.
(iv.) In galvanometer, the pointer deflects on both the sides of the zero mark depending on the direction of the current.
(v.) Galvanometer is used for detecting and measuring electric current.
