What is another word for moving-coil galvanometer?
Pronunciation: [mˈuːvɪŋkˈɔ͡ɪl ɡˌalvɐnˈɒmɪtə] (IPA) 
A moving-coil galvanometer is a device used to detect and measure small electric currents. However, there are several other terms that can be used to describe this device. Some common synonyms include a tangent galvanometer, reflecting galvanometer, and ballistic galvanometer. The tangent galvanometer is similar to the moving-coil galvanometer but uses a magnet instead of a coil of wire. The reflecting galvanometer uses a mirror to reflect light and measure small electric currents. The ballistic galvanometer is used to measure the total charge that passes through an electric circuit. All of these terms are interchangeable and refer to the same device used in electrical engineering and physics.
