Two cells of emfs approximately 5V and 10V are to be accurately compared using a poteniometer of length 400 cm.A. The battery that runs the potentiometer should have voltage of 8 VB. The battery of potentiometer can have a voltage of 15 V and R adjusted so that the potential drop across the wire slightly exceeds 10 VC. The first portion of 50 cm of wire itself should have a potential drop of 10 VD. Potentiometer is usually used for comparing resistance and not voltages
