Moving charge from one initially-neutral capacitor plate to the other is called charging the capacitor. When you charge a capacitor, you are storing energy in that capacitor. Providing a conducting path for the charge to go back to the plate it came from is called discharging the capacitor.
This article delves into the world of capacitors, explaining what a capacitor consists of, the different types of capacitors and their uses, and also discusses the importance of choosing the right capacitor for your application.
There are two capacitor symbols generally used in electronics. One symbol is for polarized capacitors, and the other symbol is for non-polarized capacitors. In the diagram below, the symbol with one curved plate represents a Polarized Capacitor. The curved plate represents the cathode (– ve) of the capacitor, and the other plate is anode ...
Capacitor Construction. A capacitor is constructed out of two metal plates, separated by an insulating material called dielectric. The plates are conductive and they are usually made of aluminum, tantalum or other metals, while the dielectric can be made out of any kind of insulating material such as paper, glass, ceramic or anything that obstructs the flow of the current.
How Capacitors Work: When connected to a battery, one plate becomes positively charged and the other is negatively charged, leading to a potential difference between two conductor plates. Capacitance: Capacitance is a capacitor''s ability to store charge per unit voltage, expressed as C=Q/V, with the unit Farad (F).
Charge on this equivalent capacitor is the same as the charge on any capacitor in a series combination: That is, all capacitors of a series combination have the same charge. This occurs due to the conservation of charge in the circuit.
Applications of Capacitors. Some typical applications of capacitors include: 1. Filtering: Electronic circuits often use capacitors to filter out unwanted signals. For example, they can remove noise and ripple from power supplies or …

The other value is our voltage which we measure in volts with a capital V, on the capacitor the voltage value is the maximum voltage the capacitor can handle. This capacitor is rated at a certain voltage and if I exceed this value then it will explode. Example of capacitor voltage. Most capacitors have a positive and negative terminal.
A 1uF capacitor and a 10uF capacitor are other common ones seen in circuits. They do a good job of helping smooth out ripple noise in DC voltages. For super capacitors, a 1 Farad capacitor or even a 2 Farad capacitor is seen often on boards that need a little current even if the power goes out or the battery dies.
(Photo Credit : Papa November/Wikimedia Commons) A capacitor is a device that consists of two conductors separated by a non-conducting region. The technical term for this non-conducting region is known as the dielectric.The dielectric can be any non-conducting element, including a vacuum, air, paper, plastic, ceramic or even a semiconductor.

Multiple capacitors placed in series and/or parallel do not behave in the same manner as resistors. Placing capacitors in parallel increases overall plate area, and thus increases capacitance, as indicated by Equation ref{8.4}. Therefore capacitors in parallel add in value, behaving like resistors in series.
