Capacitors function based on the principle of capacitance, which is the ability to store charge per unit voltage. When connected to a power source, capacitors charge and discharge according to the applied voltage and the capacitance value. Here some wide applications for capacitors in the following:
Conversely, for very low frequencies, the reactance is high, so that a capacitor is nearly an open circuit in AC analysis – those frequencies have been "filtered out". Capacitors are different from resistors and inductors in that the impedance is inversely proportional to the defining characteristic; i.e., capacitance.
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.
The capacitors each store instantaneous charge build-up equal to that of every other capacitor in the series. The total voltage difference from end to end is apportioned to each capacitor according to the inverse of its capacitance. The entire series acts as a capacitor smaller than any of its components.
Electrolytic capacitors generally have the shortest lifespans. Electrolytic capacitors are affected very little by vibration or humidity, but factors such as ambient and operational temperatures play a large role in their failure, which gradually occur as an increase in ESR (up to 300%) and as much as a 20% decrease in capacitance.
One plate of the capacitor collects a positive charge while the other collects a negative charge, creating an electrostatic field between them. This electrostatic field is the medium through which the capacitor stores energy. The amount of electrical charge that can be stored in the capacitor is determined by the capacitor’s capacitance.
