circuit for Figure shows a potentiometer measuring the internal resistance r of a cell Y When the cell is an open circuit T is the balance point on the wire PQ The resistor R is used S A B C D Y P R 1 X Ir R T Q to make the galvanometer G more sensitive to produce a long balance length because G is sensitive galvanometer to protect the potentiometer wire
