Figure shows a simple potentiometer circuit for measuring a small emf produced by a thermocouple. The meter wire PQ has a resistance of 5 ohm, and the driver cell has an emf of 2.00 V. If a balance point is obtained 0.600 m along PQ when measuring an emf of 6.00 mV what is the value of resistance R?
