In the construction of potentiometer, the length of wire used is

Describe the construction of potentiometer.

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

What will be the effect on the accuracy of the result if we replace a single-wire potentiometer by a potentiometer having 12 wires, the length of each wire being 1 m ?

The potentiometer wire of length 200 cm has a resistance of 20 Omega . It is connected in series with a resistance 10 Omega and an accumulator of emf 6 V having negligible internal resistance. A source of 2.4 V is balanced against length 1 of the potentiometer wire. Find the length l of the potentiometer wire. Find the length l
