Capacitors behave differently than resistors, where resistors allow a flow of electrons through them directly proportional to the voltage drop, and capacitors oppose changes in voltage by drawing or ...

Last month's column explained that AC current flowing through an inductance reaches its peak amplitude after the voltage. Lagging current is characteristic of an inductive circuit. Capacitive circuits ...

Occasionally a design requires capacitors that are much closer to being identical in value to one another than the usual ...

In modern industrial and household applications, single-phase motors are widely used due to their simple operation and low cost. However, effectively adjusting their speed is a common challenge. This ...

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 ...

One of the last remaining unshrinkable obstacles blocking the progress of fully integrated, wearable technology is the clunky component that absorbs and disburses stray electricity and converts ...
