The resistance of galvanometer is g ohm and the range is 1 volt. The value of resistance used to convert it into a voltmeter of ragne 10 volt is:-

A potentiometer wire of length 10m and resistance 30 ohm is connected in series with a battery of emf 2.5V, internal resistance 5 ohm and external resistance R. If the fall of potential along the potentiometer wire is 50mV/m, the value of R is ohms is

A galvanometer has a current sensitivity of 1 mA per division. A variable shunt is connected across the galvanometer and the combination is put in series with a resistance of 500Omega and cell of internal resistance 1Omega . It gives a deflection of 5 division for shunt of 5 ohm and 20 division for shunt of 25 ohm. The emf of cell is
