How is a galvanometer converted into a voltmeter? Why series resistance is greater than galvanometer resistance? Explain.

A galvanometer can be used as a voltmeter by connecting

A moving coil galvanometer can be converted into a voltmeter by connecting :

A galvanometer (coil resistance 99 Omega .) is converted into an ammeter using a shunt of 1 Omega and connected as shown in figure (a). The ammeter reads 3 A . The same galvanometer is convened into a voltmeter by connecting a resistance of 101 Omega in series. This voltmeter is connected at, shown in figure (b). Its reading is found to be 4/5 of the full scale reading. Find : (a) internal resistance r of the cell (b) range of the ammeter and voltmeter (c) full scale deflection current of the galvanometer.

To convert a galvanometer into a voltmeter, one should connect a

(a) Briefly explain how a galvanometer is converted into a voltmeter. (b) A voltmeter of a certain range is constructed by connecting a resistance of 980 Omega in series with a galvanometer. When the resistance of 470 Omega is connected in series, the range gets halved. Find the resistance of the galvanometer.

In Q.36 , the combined resistance of the shunt and the galvanometer is

(a) Briefly explain how a galvanometer is converted into an ammeter. (b) A galvanometer coil has a resistance of 15 Omega and it shows full scale deflection for a current of 4 mA. Convert it into an ammeter of range 0 to 6 A.

STATEMENT-1 : Galvanometer can be converted into voltmeter by connecting a large shunt in its series. STATEMENT-2 : Galvanometer can be converted into an ammeter by connecting a small shunt in its parallel. STATEMENT-3 : Galvanometer cannot be converted into voltmeter or ammeter.

A galvanmeter of resistance G is converted into a voltmeter of range 0 -1V by connecting resistance R_1 in series with it. The additional resistance that should be connected in series with R_1 to increase the range of the voltmeter to 0-2 V will be :
