How Capacitors Work
          
  • Capacitors used in electronic circuits or DC voltage insulation blocking, and use it with coils produce resonant circuits or intentional transmission of AC signals, filtering unwanted Interference filters and smooths the power supplies equally.

  • Construction of the basic capacitor It consists of two plates (conductors),that are separated by a dielectric (insulator). Material can be isolated Mika Paper, tantalum, plastic, fiber, or even air.

  • Capacity (in micro farads or pico farads) determines the size of the electric charge Q Capacitors can store (hold).
  • Capacity is determined by the size of the plates, space between the plates, and type of dielectric material between the plates.
