The impact of capacitors on power
Why the Capacitor in Your Power Supply Filter is Too Big
The general idea of the design is that we want all of the ripple power ([P_{o}cos(2omega t)]) to flow back and forth to the ripple port capacitor. To get this to happen, we need the ripple power equation to match the equation for the power to a capacitor. The equation for the power to a capacitor in a sinusoidal AC circuit is

Capacitor in Electronics
A capacitor is an electrical component that stores energy in an electric field. It is a passive device that consists of two conductors separated by an insulating material known as a dielectric. When a voltage is applied across the conductors, an electric field develops across the dielectric, causing positive and negative charges to accumulate …
Capacitor ESR Effects
Now let''s calculate power dissipation in the example. The peak current at 1 amp, DF at 20%, and ESR at 1 ohm, the capacitor sources 0.32 amps RMS. Its power dissipation is 102 mW, there should not be a problem in this case. If you asked that single capacitor to source 10 amps peak, keep the fire extinguisher handy, it would dissipate 10 watts!
