A potentiometer is essentially a resistor with three contacts, one of which is mobile. It acts as a variable resistor, since changing the position of the mobile contact, called the "wiper" (denoted by an arrow), changes the amount of the resistor through which current must pass. The circuit shown consists of one 93.7 V battery, one fixed resistor with resistance Ri = 1780 N, and one potentiometer. In addition, one of the wires is grounded (at zero potential). The resistive...
