A battery of e.m.f 3.0V is connected across a potentiometer wire AB of 10m.If the jockey J makes contact at the 30cm mark, determine the resistance of length AJ and voltage across AJ

Question

Harshit Singh · Answer

Dear student E = 3.0V; R / l =10&Omega; per m l = 30cm = 0.3m; R =10&Omega; per m &times; 0.3m = 3&Omega; Thus , Resistance of AJ = 3 ohms E / V = l1/ l2 ⟹3 / V = 1 / 0.3 =3&times;0.3 Hence , Voltage across AJ = 0.9V Thanks
