Apr 20, 2010 · If powered by the AC line, assuming full-wave rectification, the capacitor must supply current to the regulator for 1/2cycle (8.3ms or 10ms, depending if it is 60Hz or 50Hz) The Charge Q (Coulombs) removed from the capacitor is Q=I*t, where I is current and t is time.
This capacity or "tank size" is measured in Farads. Will a Power Capacitor Help You? I don't know, it depends. How's that for an answer? The degree of help a power capacitor will give you depends on your specific vehicle, car audio amplifier(s) current draw, music type and listening habits.
Two capacitors with capacity C1 and C2 are charged to potential V1 and V2 respectively and then connected in parallel. Calculate the common potential across the combination, the charge on each capacitor, the electrostatic energy stored in the system and the change in the electrostatic energy from its initial value.
5: Capacitors July 8, 2008 5.1 Definition A capacitor is a structure which has a certain capacity to hold an electric charge. It is essentially the simplest possible battery. The typical example of a capacitor, and the typical actual design, is two parallel charged plates. There are variations and clever extensions, but this is the basic idea, and
