A 10kO potentiometer sensor is used to measure displacement and is connected to a voltage source of 5V. The full range of the displacement is 10mm. When the potentiometer is at 4mm of its maximum displacement, determine:
a. The output resistance of the potentiometer, assuming the load is infinite.
b. The output voltage, assuming the load is infinite.
c. The non-linearity error as a percentage of full output range when the load resistance is 47kO.
d. The minimum value of the load resistance if the maximum non-linearity error of the potentiometer is 0.1% of full output range (load resistance RL>>Rp resistance of the potentiometer).
