Problem: Consider the linear displacement potentiometer
circuit diagram shown. The input voltage Vin is 5 Volts, and
the output voltage Vout is 2.5 Volts. The total resistance
element length is 100 mm, so when the sliding contact is at the
centre, the distance AB=BC=50 mm
The linear displacement of an object causes the sliding contact
to move such that the output voltage changes to 2.65 Volts.
Determine the displacement of the object and the direction in
which it moves.
