Capacitance Presentation

capacitance

capacitance

It is designated as the quality that certain elements possess to absorb and store energy or electrical charge. Its unit of measurement is the Faradin (F), named after the English physicist Michael Faraday (1791-1867). As an example we can find batteries and capacitors, with the difference in the response and type of charge and discharge.

structure

In general, they are made of 2 metal plates or sheets separated by a dielectric material. When they are electrically powered, these plates are charged, generating a voltage between them that will be expelled or discharged when they have a consumption. The units that capacitors commonly found are in the order of micro(uF) and picofarads (pF), since this unit of measurement is very large.

symbology

Types

They differ by capacitance value, sensitivity, manufacturing materials, application of use, and whether or not they are polarized. This last characteristic is of great importance as it can lead to injuries, if not taken into account.

Capacitor Capacity

It is the amount of charge that a capacitor can store and is expressed:

W= q2/ (2C)= (C*V2 )/2 = (q*v)/2

C= q/V Where: q:Stored Charge in Coulomb V: Potential Difference in Volts

W: Power in a Joules Capacitor
