Capacitor Summary

The capacitor is a partial summary of the general capacitor information that we have passed on to you so far in our summary content.

Capacitors consist of two metal plates separated by a dielectric.

Capacitors areenergy storage devices that can store electrical charge along their plates.Socapacitors store energy due to their load storage capabilities andthe capacitor does not lose the energy it stores.

The simplest structure of a capacitor is to use two parallel conductive metal plates separated at a certain distance with an insulation material called dielectric, as outlined below.

  • A capacitor consists of two metal plates separated by a dielectric.
  • It can be made of many insulating materials such as dielectric, air, glass, paper, plastic, etc.
  • A capacitor can store electrical charge and energy.
  • The higher the capacitance value, the more load the capacitor can store.
  • The larger the area of the plates or the smaller their range, the more load the capacitor can store.
  • It is said that a capacitor is "Fully Charged" when the voltage on the plates is equal to the feed voltage.
  • The symbol of the electric charge is Q and its unit is Coulomb.
  • Electrolytic capacitors are polarized.It has + and – poles, and the connection must necessarily be made between the same poles.
  • The farad, which is the capacitance unit of measure, is a very large unit, so micro Farad ( uF ), nano Farad ( nF ) and pica-Farad ( pF ) are generally used.
  • It is said to be serially connected to capacitors that are chained together on a line.
  • Both terminals are called parallel connected to capacitors connected to the same terminal of another capacitor.
  • Parallel connected capacitors have a common feeding voltage between them.
  • There is a common current passing through the serial connected capacitors.
  • Capacitive reactaxiation is a contrast to current flow in XC , AC circuits.
  • In AC capacitive circuits, the voltage "outperforms"the current by 90.

The basic structure and symbol of a capacitor with parallel plates are given as follows:
