If you enjoy building radio projects you may have noticed something slightly worrying over the last few years in your component supply. Variable capacitors are no longer as plentiful as they used to ...

OBJECTIVE: You will wind (and test) your own inductor, which you will also use in the AM radio project in a subsequent lab. You will also investigate the properties of capacitors by making a simple ...

The capacitor is one of the most important electrical components, and we’ll learn how it works in this second part of the basic electronics course for kids. It will be explored in terms of energy ...

What would MacGyver do if he needed a high voltage capacitor but only had some foil, tape, water, salt, a nail and a plastic jug? He would build a salt water Leyden jar, that’s what. The Leyden jar is ...
