What is a galvanmeter?

Answer 1

A galvanometer is an instrument used to detect and measure small electric currents by utilizing electromagnetic principles. It typically consists of a coil of wire suspended in a magnetic field, where the current passing through the coil generates a torque that causes it to deflect. The degree of deflection is proportional to the strength of the current, allowing for precise measurements. Galvanometers are often used in laboratories and educational settings, as well as in various electronic devices.
