How a galvanometer works

WebA mirror galvanometer is an ammeter that indicates it has sensed an electric current by deflecting a light beam with a mirror. The beam of light projected on a scale acts as a long massless pointer. In 1826, Johann Christian Poggendorff developed the mirror galvanometer for detecting electric currents. WebIt measures the tiny trickle of current which the potential difference drives through a high resistance inside the voltmeter's case. To convert your galvanometer to a voltmeter reading, say, 5 V when the pointer is at the end of the scale, you must add a large resistance in series, as in the diagram. The galvanometer itself has only a small ...

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) × … 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.
