Electronic components and what they do

Videos on electronic components and what they do. Connecting several together (the right way)
brings them to life in a circuit which forms the basis of every piece of electronic equipment.

A look at switches


Fun with variable resistors


Different types of capacitors


Make your own capacitor with stuff from the kitchen


An introduction to variable capacitors


Fun with neon lamps


Back to basics with flashing LEDs


A 'reverse avalanche mode' transistor LED flasher
