What's Capacitor and Construction - Symbol Diagram

As you known that capacitor are numbering in those electrical and electronics component which we use very much in different circuits for different uses. In this post i am just writing about that what capacitor and how it's works.

Capacitor Definition and Explanation


Capacitor (Cap) is a component which consists of conducting surface separated by by a non-conductive region or by a layer of on insulating me dim called dielectric. Note that the non-conductive region mean also dielectric.
or An example of dielectric is that it's a electrical insulator. I.E example is glass, air, paper, vacuum can be use as dialectic in capacitor.

The purpose of capacitor is that to store electrical energy by using electrostatics. capacitor can better explain by below definitions.




  • In simple words a Cap is an electronic component which can story the electrical energy from of electrostatic field is called Cap... or condenser. Note that we also called condenser to Cap...
  • A device which is consists with two metal plates, in which any insulating medium use between palates as dielectric is called cap....
  • If we place two conductor plates near with one another and place a insulating material between the plates and provide the electric charge to plates from potential difference source (voltage) source is called Capacitor.
  • Any two conductors in which electric flied can be maintained is a from of cap..
  • In  simple words a CAP is a electrical device which is consists two conductive plates in parallel and which is separated by an insulating material is called dielectric.

In capacitor we have connecting leads which is connected to these parallel conductive plates. In the blow diagram i shown internal structure - construction of capacitor and it's circuit symbols.

capacitor structure and capacitor symbol diagram


In the above diagram i shown the Cap symbols which we use in circuit for Cap. If we have an paralleled plate type of CAP. So one plate supply wire is connected to positive end and other is to negative or earthed. When we connect link of this type of  Capacitor to the battery supply. So the electron flow start from plate A to plate B for a time. (It's happened because Plate A can bearer more charge due to plate B earthed)
Due the negative electron emission from plate A and Plus to B plate. Due this electron emission- the positive charge on plate A and negative charge on Plate B.
