A two-meter potentiometer wire is used in an experiment to determine the internal resistance of a Voltaic cell. The emf of the cell is balanced by the fall of potential along 90.6cm of the wire. When a standard resistor of 10ohms is connected across the cell the balance length is found to be 75.5cm. Draw a labelled circuit diagram and calculate from first principles, the internal resistance of the cell
