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