Large power supplies that operatefrom ac wall voltage havelarge input-filter capacitors. You mustlimit the inrush current to those capacitors.Otherwise, the supply may tripthe ac circuit breaker, or ...

For a pure capacitor or inductor, the real part is zero. Real circuits will have combinations and thus will have a combination of real and imaginary parts.

What happens when you connect a charged capacitor to an inductor? You get an oscillating circuit. Here's how it all works.

Capacitors connected from line to neutral provide reactive power to an AC circuit, which is measured in volt-amperes reactive (VARs). For a given value of capacitance, more VARs are supplied as the ...

That’s fine for DC current through resistors. But components like capacitors and inductors with an AC current don’t obey Ohm’s law. Take a capacitor.

This is the simple version of a white LED lamp that can be directly powered from mains. It can give ample light even for reading purpose. Capacitor Cx along with diodes D1 through D4 forms the AC step ...
