A) NEED homework help? Click here. 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 PLZ mark it as brainlist |
