Question

Write a short note on the galvanometer.

Answer 1

1. A galvanometer is a sensitive device that works on the principle that a current-carrying conductor placed in a magnetic field experiences a force.
2. The pointer on the galvanometer dial is connected to a coil.
3. 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.
4. In galvanometer, the pointer deflects on both sides of the zero mark depending on the direction of the current.
5. A galvanometer is used for detecting and measuring electric current.
