Galvanometer

A Galvanometer is an instrument used to detect and measure small electric currents by deflecting a needle or pointer in response to the current flow. Key features of a Galvanometer: Consists of a coil of wire suspended in a magnetic field. When current passes through the coil, it experiences a torque causing the needle to move. The needle's deflection is proportional to the current magnitude. Used in laboratories and electrical measurements to detect and measure low-level currents. Can be modified into devices like ammeters and voltmeters with additional components. Essential tool for studying electrical circuits and calibrating instruments. Galvanometers provide precise and sensitive current measurement in electrical and electronic applications.
