while that with the unknown resistance X is 68.5 cm. Determine the value of X. What might you do if you failed to find a balance point with the given cell of emf ϵ? ,
A voltage V0 is applied to a potentiometer whose sliding constant is exactly in the middle. A voltmeter V is connected between the sliding constant and one fixed end of the potentionmeter. If is assumed that the resistance of the voltmeter is not very high in comparison to the resistance of the potentiometer wire. What voltage will the voltmeter show : higher than, less than, or equal to V0/2?

Figure shows a 2.0 V potentiometer used for the determination of internal resistance of a 1.5V cell. The balance point of the cell in open circuit is 76.3cm. Whan a resistor of 9.5Ω is used in the external circuit of the cell, the balance point shifts to 64.8 cm, length of the potentiometer. Determine the internal resistance of the cell.
