Solution :
The fall of potential across a potentiometer wire of length l is given by
V=IRV=IR
=IρlA=IρlA
Potential gradient k=vl=IρAk=vl=IρA
=k∞I=>=k∞I=> current passing through the potentio meter wire.
(ii) k∞ρk∞ρ (ie) specific resistance of the material of the potentiometer wire.
(iii) k∞1Ak∞1A
(ie) area of cross section of the wire
hope it helps
