Galvanometer - Voltmeter, Ammeter and Ohmeter - Animation
A galvanometer is an electromechanical instrument for detecting and indicating electric current. A galvanometer works as an actuator, by producing a rotary deflection (of a "pointer"), in response to electric current flowing through a coil in a constant magnetic field.
