A series high resistance is preferable than shunt resistance in the galvanometer circuit of potentiometer. Because

Find the expression for the shunt resistance in a circuit where galvanometer is converted into ammeter

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

If a galvanometer is connected in series with a high resistance so that potential drop across the galvanometer is 1/n th of the total applied voltage, then show that the combined resistance of the galvanometer and the series resistor is n times the resistance of the galvanometer i.e.,

Sensitivity of potentiometer can be increased by a) increasing series resistance in the primary circuit b) decreasing the length of potentiometer wire c) using thin and high resistivity wire as potentiometer wire d) increasing the length of the wire

In a galvanometer 5\% of the total current in the circuit passes through it. If the resistance of the galvanometer is G, the shunt resistance S connected to the galvanometer is

The function of high resistance connected in series with the galvanometer in voltmeter is
