Capacitors
Variable capacitors may be useful, but the air gap that provides their capacitance is their greatest weakness. Rather than deal...
If you’ve seen a big air-variable capacitor, you may have noticed that some of the plates may have slots cut...
Radio experimenters often need a variable capacitor to tune their circuits, as the saying goes, for maximum smoke. In decades...
