There’s one component which used to be ubiquitous in every experimenter’s junk box, but nowadays unless you happen to be a radio amateur the chances are you may not have seen one in a long time, if ...

Radio experimenters often need a variable capacitor to tune their circuits, as the saying goes, for maximum smoke. In decades past these were readily available from almost any scrap radio, but the ...

Variable capacitors are electronic components that allow for the adjustment of capacitance within a circuit. They are designed to store and release electrical energy, with the unique feature of being ...

The first British commercially available high-vacuum variable capacitors have been announced by the English Electric Valve Co. So 64 years ago, started a story in Electronics Weekly’s edition of March ...

How do you implement a variable capacitor these days? Mechanical caps are out. That leaves varactors, which work fine but require higher voltages that often are not available, and their response is ...

Capacitors are passive electronic components that store electrical energy. Basic capacitors, formerly known as condensers, consist of two parallel plates - one positive and one negative - separated by ...

Marked: "Dayton Fan & Motor Co. / Dayton, Ohio, U.S.A. / Day-Fan". A Variable capacitor with six fixed plates and six movable plates. Arrangement of plates permits interleaving of sets of three each, ...

Aluminum? Ceramic? Film? Mica? The best type of capacitor for your circuit isn’t always clear, but this list of 17 common capacitor applications will help you narrow it down. Capacitors are one of the ...

Capacitors are a crucial component of any electrical circuit, and every engineer should know how they work and when to use them. But as with every electronic component, there’s a lot to understand ...
