Galvanometer is used to detect presence of small current in a circuit.
Use of galvanometer
- A galvanometer is an electromechanical system that detects and displays an electric current.
- A galvanometer generates a rotary deflection of a pointer in response to electrical current flowing through a coil in a continuous magnetic field, acting as an actuator.
- A galvanometer is a device that detects weak electrical voltages and currents in a circuit.
- It has a coil of a solid laminated horse shoe magnet pivoted between concave pole faces. If an electrical current passes through the coil, it deflects.
