Welcome to the Analogue Electronics category. In this set of tutorials we will cover all things analogue, from simple voltage sources to complicated amplifier circuits. Like the physics tutorials, these tutorials aren’t aimed at hobbyists as the content is not necessary to use electronics; they are written for students to revise with. They are also aimed at experienced hobbyists or engineers as a reference to things they may have forgotten since learning it.

For the first half of the tutorials we will start by looking at simple circuit laws: Kirchoff’s laws, current and voltage dividers and resistance laws. We will then look at equivalent circuits, some mesh and nodal analysis and finally at Reactive and Resistive circuits (dealing with Phasors). The second half of the tutorials will focus on amplifier circuits, first using transistors, then using FETs and finally with the Op-Amp.

The content in these tutorials is a lot more complicated than hobbyists require and so it’s best not to get too worried if you don’t understand what’s going on. If you are a student or professional engineer on the other hand and there’s something you don’t understand then leave a comment and we (and no doubt other users) will do our best to answer them in an easy-to-understand kind of way.

So let’s go…
