👉 Galvanometers are a type of electromechanical instrument that measures electric current. They work by converting the electrical voltage to an electromotive force (EMF), which can then be used to measure the magnetic field produced by the magnet in the galvanometer's coil. This EMF is proportional to the current flowing through the wire, and thus the galvanometer shows a linear relationship with the applied voltage. Galvanometers are commonly used in electrical measurement systems for measuring electric currents or voltages
