Capacitor

An electric fan needs a large amount of electrons is order of function. What device do they use in order to provide the necessary electrons? They use CAPACITORS.

Capacitor is an electronic device that stores  electrons. It is made up of two conductors separated by an insulator , or dielectric. A capacitor is measured in “Farads”. But one farad is already a huge amount of electrons to be exact. So they usually measure capacitors in microfarads or picrofarads. A one picofarads is equal to 0.000000000001 Farad, and one microfarad is equal to 0.000001 Farad.

Capacitors may either Non-polarized capacitor, polarized capacitor, variable capacitor or either Trimmer Capacitor. a Non-polarized capacitor is a capacitor that can be connected in anyway we can desire, for there is no positive or either negative. It may use as a filter to block PC signals but to pass AC signals. Polarized Capacitor is a capacitor that stores electric charge. It has positive and negative so it should be connected in a correct way. It can also be used as a filter to block DC signals but to pass AC signals. A variable capacitor is a capacitor which can be vary its capacitance by moving the plates. It is commonly used in a radio turner. Trimmer capacitor is designed to be set when the circuit is made and then left without further adjustment. Capacitor come in different variety.
