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.
