The SI unit of a moving coil galvanometer is the **ampere (A)**.
A moving coil galvanometer is used to measure small electric currents, and its sensitivity is typically expressed in terms of the current (in amperes) required to produce a specific deflection. While the unit of measurement for the current is the ampere, the galvanometer itself is calibrated to detect current and provide a corresponding reading based on the deflection of its needle or scale.
