Capacitors are small devices used to store electric charges and consist of one or more pairs of conductors separated by an insulator. They’re mainly used in energy-storing devices such as televisions, ...

Once upon a time I was a real mad scientist. I was into non-conventional propulsion with the idea of somehow interacting with the quantum vacuum fluctuations, the zero point energy field. I was into ...

Many power supplies use hold-up capacitors to keep enough energy at the full-wave or bridge rectifier output to supply a load when the rectified voltage drops and rises again at the next half-cycle of ...
