WebA galvanometer may be converted into an ammeter by connecting a low resistance (called shunt) in parallel to the galvanometer. g g I I I G S Where, G = resistance of the galvanometer Ig= full scale deflection current of the galvanometer I = maximum current to be measured by the ammeter. or R 1 R 3 R 2 R 4 Potentiometer WebCount the total number of divisions on either side of zero of the galvanometer scale. Let it be n. Calculate the current (I g) for full-scale deflection i.e., I g = nk. Calculate the value of shunt resistance, for conversion into ammeter, using the formula, where I …
A tangent galvanometer has a coil of 25 turns and a radius of
WebA galvanometer has a resistance of 5Ω. By using a shunt wire of resistance 0.05Ω, the galvanometer could be converted to an ammeter capable of reading 2Amp. What is the current through the galvanometer? WebCoil Instrument or PMMC Instrument. Galvanometers Electromechanical Voltmeters and Ammeters.

WebTo convert a moving coil galvanometer to a voltmeter, we add a high series resistance, but why?. The high resistance causes most of the voltage to drop across it, leaving a small … WebN divisions of converted galvanometer = V volt. The least count of the converted galvanometer, L.C =V/N Hence, we can convert the reading of galvanometer to volts using the relation V G = n x L.C V G = Potential difference in volts n = No. of divisions in galvanometer L.C = Least count of the converted voltmeter http://www.amrita.olabs.edu.in/?sub=1&brch=6&sim=26&cnt=1 dwain burns
