Resistors are omnipresent in your everyday life. A light bulb is basically a resistor. But also the heating element in your toaster is a resistor. However they can do even more. They limit current, divide voltage and consume excess energy.
On the following pages you get to know resistors. With simple circuits you get to know the basic characteristics. Thereafter you build resistors in applications that further explain the functionality.
Before you can start with the first experiments, please make a few preparations.
