Description
A galvanometer is a laboratory instrument used to measure small electrical currents. It consists of a coil of wire suspended in a magnetic field, with a pointer attached to the coil that moves in response to the current passing through the coil. The pointer indicates the magnitude and direction of the current.
Galvanometers are sensitive instruments and are typically used for measuring small currents, such as those produced by biological signals or in electronic circuits. They are also used as part of more complex instruments, such as oscilloscopes and multimeters, for measuring various electrical parameters.
