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 ...

Capacitors fail. It’s what they do. Aluminum electrolytics caused my monitor power supply to fail. A failed capacitor took down Paul Rako’s air conditioner. This is a story of how two burned ...
