All the Galvanometer Questions & Answers given below includes solution and link wherever possible to the relevant topic. 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?
