Potentiometers and the Wheatstone Bridge

Introduction and Theory:

• A potentiometer is a variable resistor consists usually of a turning dial to change the value of its resistance between two of its terminals.
•  The resistance between the wiper (b) and either side of the outer terminals (a or c) varies from zero to a maximum of the full rating of the POT.

R_max = R_ac = R_ab + R_bc

• A Wheatstone bridge is a circuit used to measure the resistance of an unknown resistor.
