Capacitors
A capacitor is a device that stores energy in the electric field created between
a pair of conductors on which equal but
opposite electric charges have been placed. Intentional capacitors have thin
conducting plates (usually made of metal)
stacked or rolled to form a compact device, but every multi-conductor geometry
has capacitance.
Capacitors are
often classified according to the material used as the dielectric with the
dielectrics divided into two broad
categories: bulk insulators and metal-oxide films (so-called electrolytic
capacitors).
Capacitors are
connected in parallel with the power circuits of most electronic devices and
larger systems (such as
factories) to shunt away and conceal current fluctuations from the primary power
source to provide a "clean" power supply for
signal or control circuits. Audio equipment, for example, uses several
capacitors in this way, to shunt away power line hum
before it gets into the signal circuitry. The capacitors act as a local reserve
for the DC power source, and bypass AC
currents from the power supply.
