How is a galvanometer and an armature alike
Galvanometer mechanisms are divided into moving magnet and moving coil galvanometers; in addition, they are divided into closed-loop and open-loop - or resonant - types. Mirror galvanometer systems are used as beam positioning or beam steering elements in laser scanning systems.

Web20 aug. 2024 · Both the Galvanometer & ammeter are measuring devices but the main difference between these two devices is that the galvanometer is mainly used to compute very little current whereas the ammeter is mainly used to determine a very high current equal to 10 A. So these two devices are the measuring devices. WebArmature: the coil of wire that the current flows through. It will often have many coils inside the external magnetic field before it exits. Armatures are sometimes called rotors. …
WebArmature (electrical) A partially-constructed DC armature, showing the (incomplete) windings. In electrical engineering, the armature is the winding (or set of windings) of an electric machine which carries alternating current. [1] The armature windings conduct AC even on DC machines, due to the commutator action (which periodically reverses ...
