This is helpful for users who are preparing for their exams, interviews, or professionals who would like to brush up on the fundamentals of the galvanometer. The galvanometer is a type of electromechanical device which is categorized into two types they are pivoted coil and suspended coil galvanometers. It is one type of instrument which uses a magnetic field, measures simply DC and they are more responsive. The galvanometers are invented in 1802 by Johann Schweiger, the unit of galvanometers is radian/ampere or division/ampere. The suspension, stable magnet, and moving coil are the parts of the galvanometer. The galvanometers are highly reliable, accurate, and highly sensitive. In a dead-beat galvanometer, the coil is wound on a conducting frame, and this dead-beat galvanometer is used for deflection of current. In a dead-beat galvanometer, the coil stops oscillating when the circuit switches off. In a ballistic galvanometer, the coil is wound on a non-conducting frame, and the ballistic galvanometer is used for deflection of charge. In a ballistic galvanometer, the coil keeps on oscillating even if the circuit-switched is off. 1). Which one of the following galvanometers used for deflection of current?
