This page lists some of the most popular electronics downloads available from learnabout-electronics.org. Did you know that there are over 500 pages of electronics know-how available to download and print, in 30 different Modules, just click the "DOWNLOAD MODULE" pdf logo on any module, and it is yours to print and keep.
Many of the modules also use animations to better illustrate electronic circuits and component actions. The Flash animations are ideal for use on desktop computers, projectors and whiteboards, just click the the "FULL SCREEN" button for a full size display. Note: Some animations contain elements (such as slider controls) that do not work well on touch screens, where this may be the case, the downloads are marked with an asterisk*.
A4 Handout on how to test transistors, a simple step by step transistor testing guide using digital or analogue multi-meters. Identify common transistor package types and pin connections from suppliers datasheets.
Transistors as Amplifiers.
There are three ways a transistor can be used as an amplifier. How the transistor is connected affects the way the amplifier works. This is a quick guide explaining the effects of the different connection methods. A4 Handout.
