Filter Capacitor : Circuit, Working, Formula and Its Applications
What is a Filter Capacitor : Working and Its Applications
8.2: Capacitance and Capacitors
Capacitors are available in a wide range of capacitance values, from just a few picofarads to well in excess of a farad, a range of over 10(^{12}). Unlike resistors, whose physical size relates to their power rating and not their resistance value, the physical size of a capacitor is related to both its capacitance and its voltage rating (a consequence of Equation ref{8.4}.
What is Capacitance
What is Capacitance Capacitance is a measure of an object''s ability to store electrical charge when a potential difference (voltage) is applied across it. It is defined as the ratio between the amount of energy stored in an object and the amount of charge applied to it.
8.2: Capacitance and Capacitors
Equation ref{8.6} provides considerable insight into the behavior of capacitors. As just noted, if a capacitor is driven by a fixed current source, the voltage across it rises at the constant rate of (i/C).

Capacitor
OverviewHistoryTheory of operationNon-ideal behaviorCapacitor typesCapacitor markingsApplicationsHazards and safety
In electrical engineering, a capacitor is a device that stores electrical energy by accumulating electric charges on two closely spaced surfaces that are insulated from each other. The capacitor was originally known as the condenser, a term still encountered in a few compound names, such as the condenser microphone. It is a passive electronic component with two terminals.
18.5 Capacitors and Dielectrics
Although the equation C = Q / V C = Q / V makes it seem that capacitance depends on voltage, in fact it does not. For a given capacitor, the ratio of the charge stored in the …
CAPACITOR BANKS
Figure 2 – Schematic diagram of a capacitor bank Capacitors may retain a charge long after power is removed from a circuit; this charge can cause dangerous or even potentially fatal shocks or damage connected equipment. Capacitors banks may have built-in discharge resistors to dissipate stored energy to a safe level within a few seconds after …
