Galvanometer For Class 12 Pdf — Project File On Moving Coil

Voltage across shunt = Voltage across galvanometer [ I_g \cdot R_g = (I - I_g) \cdot S ] [ S = \fracI_g R_gI - I_g ]

Let ( I ) = total current to be measured, ( I_g ) = full-scale deflection current of galvanometer, ( R_g ) = galvanometer resistance. project file on moving coil galvanometer for class 12 pdf

A low-range galvanometer becomes a high-range ammeter. 8. Conversion into Voltmeter To measure voltage, a high resistance (( R )) is connected in series with the galvanometer. Voltage across shunt = Voltage across galvanometer [
