Capacitor

  1. 1. What is Capacitor?
  2. 2. A device that stores electrons.The basic capacitors is made up of two conductors separated by an insulator or dielectric.
  3. 3. Depending on how the capacitor is built, the dielectric can be made of papers, plastic, mica, ceramic, glass, a vacuum or any other such non conductive material.
  4. 4. Capacitors come in variety of sizes, shapes, models, or if you so desire they can be manufactured by your specifications.
  5. 5. The value of a capacitor can vary from a fraction of a pico-Farad to more than a micro Farad.Voltage levels can range from a couple to a substantial couple of hundred thousand volts.
  6. 6. TYPES OF CAPACITOR
  7. 7. •Non-polarized capacitor •Polarized capacitor •Variable capacitor •Trimmer capacitor
  8. 8. Non-polarized capacitor
  9. 9. Type of capacitor that can be connected any way in a circuit.There is no positive or negative. Common types of non-polar capacitors are ceramic, mica and some electrolytic.
  10. 10. A capacitor is used with a resistor in a timing circuit. It can also can be used as a filter, to block DC signals but pass AC signals.
  11. 11. Polarized capacitor
  12. 12. A capacitor stores electric charge.This type must be connected the correct way round. A capacitor is used with a resistor in a timing circuit. It can also be used as a filter, to block DC signals but pass AC signals.
  13. 13. Variable capacitor
  14. 14. A capacitor whose capacitance can be varied. These are usually made up of one or more moving plates and one or more non moving plates separated by the dielectric. By moving the plates, we can vary the capacitance. And it is used in a radio tuner.
  15. 15. Trimmer capacitor
  16. 16. This type of capacitor is operated with a small screwdriver or similar tool. It is designed to be set when the circuit is made and then left without further adjustment.
  17. 17. Capacitor can be used in charge pump circuits as the energy storage element in the generation of higher voltages than the input voltage. Capacitors are connected in parallel with the
  18. 18. *Capacitor can be used in charge pump circuits as the energy storage element in the generation of higher voltages than the input voltage. *Capacitors are connected in parallel with the DC power circuits of most electronic devices to smooth current fluctuations for signals or control circuits.
