A 80-turn potentiometer with a calibrated dial (120 divisions per turn ) is used as a
balance resistor in a Wheatstone bridge. If the potentiometer has a resistance of 36 k2 and a
resolution of 0.06 percent. What is the minimum incremental change in resistance AR that can be
read from the calibrated dial?
AR =2
