#### Question

Figure 3.34 shows a potentiometer circuit for comparison of two resistances. The balance point with a standard resistor *R* = 10.0 Ω is found to be 58.3 cm, 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*?
