This section shows how electronic components are used to make the devices we use every day. This subject often involves physics and deals with the real physical processes in matter. If you know nothing of physics it may be worth reading our Introduction to Electromagnetism section first.
Volts, Amps and Watts
These are common electronic terms are units of potential difference or EMF, Current, and Power, but what do they mean and how are they useful? This section explains the differences in the above terms and introduces some others.
Information about the range of major analogue and digital electronic components, how to recognise them, what they are used for, and the symbols used in circuit diagrams.
How components can be brought together to perform a useful function. This section show you how components interact and gives a few example circuits.
