Web20 aug. 2024 · So, a galvanometer is used for identifying the current flow within in the circuit. These are electro-mechanical devices that are not only used for detecting the flow of current as well as it measures the current within a circuit/conductor. This instrument also performs an ammeter function through a small change in it can be converted into an ... WebA galvanometer can be converted into a voltmeter of certain range by connecting a resistance of \( 980 \Omega \) in series with it. When the resistance is \(...
How galvanometer can be used as voltmeter and ammeter?
Web1 mrt. 2024 · A moving-coil galvanometer is converted into an ammeter by reducing its effective resistance by connecting a low resistance S across the coil. Such a parallel low … WebAmmeter detects both direct and alternating currents. Galvanometer detects only direct current. For an ammeter, the magnetic field is not required. The functioning of a galvanometer requires a magnetic field. Ammeter is connected in series with the circuit directly. Using the potentiometer, the galvanometer measures current. tti distribution center gaffney sc
