KNOWN: A linear potentiometer having D = 0.1 mm e = 1.7 10-8 -m R = 1 k FIND: a) for a core diameter of 1.

KNOWN: A linear potentiometer havingD = 0.1 mmρe = 1.7 × 10-8 Ω-mR = 1 kΩFIND:a) for a core diameter of 1.5 cm, determine the rangeb) plot loading error as a function of displacementCould you please help explain how to get b)

We expect the linearity till the current drawn by the potentiometer is zero from the circuitthelinearity is affected by the wiper current. The figure shows the relation of wiper current , contact...
