Moving coil of galvanometer
NettetMoving coil galvanometer works on the principle that a current-carrying coil placed in a magnetic field experiences a torque. It is an instrument which is used to measure electric currents. It is a sensitive electromagnetic device that can measure low currents even of the order of a few microamperes. Nettet13. apr. 2024 · The galvanometer can also be connected to other electrical components to form various measuring instruments, such as ammeters and voltmeters. In summary, a moving coil galvanometer works on the principle of the interaction between magnetic fields. The current flowing through the coil produces a torque on it, causing it to rotate, …
