WebTherefore we write, Sensitivity = dθ/di. If a galvanometer gives a larger deflection for a small current it is a sensitive galvanometer. The current in Moving Coil galvanometer is: I = (C/nBA) × θ. Therefore, θ = (nBA/C) × … Web6 de abr. de 2024 · Function of Galvanometer. We consider a coil to have many turns and place it in a very strong magnetic field. The reason is the more the number of turns, the …
A galvanometer is an electromechanical measuring instrument for electric current. Early galvanometers were uncalibrated, but improved versions, called ammeters, were calibrated and could measure the flow of current more precisely. A galvanometer works by deflecting a pointer in response to an electric current flowing through a coil in a constant magnetic field. Galvanometers can be thought of as a kind of actuator. Web21 de jan. de 2024 · Question 38 Explain how a galvanometer works. Answer: A galvanometer is a device which measures electric current. A needle is held in place …
