A variable resistor is very important. It allows you to build a circuit with some degree of control. For example, a volume knob can be a variable resistor. It can act as a control on the amount of current flowing. Here is a picture of a variable resistor from a dimmer switch. A variable resistor works by adjusting the path that current has to flow. Inside the resistor is a strip of metal or conducting ceramic which is connected to one part of the circuit. The dial you turn will move another piece of wire inside the resistor.
