How To Understand And Operate Capacitors

An electronic novice always finds it very difficult to understand regarding the many electronic parts that are today flooded in the market.
Take for example the capacitor. Though the component may look quite straight forward, it’s hugely classified into various types, functions, specifications etc. making the situation absolutely baffling for anybody who may be new to the field. This makes it difficult how to understand and operate capacitors.
However understanding capacitors becomes pretty easy if you study the types closely through a step wise manner as explained below:
Basically as we all know a capacitor has a couple legs which

when subjected to a voltage source either blocks the energy or allows it to pass. If the source is a DC, it’s blocked. If it’s an AC, the supply is allowed to pass, though this passage is restricted as

per the value and the reactance of the capacitor.
An electrolytic capacitor is polarized,. That means its legs are required to be oriented as per the shown polarity over its body (usually with minus sign). The voltage written over it is the breakdown voltage, means this value should never come close across its leads. These have usually high capacive values (in µF).
Other capacitor like a ceramic or disc are usually of very low capacitive values and are usually rated at over 50 volts. They may be calculated in pF or nF. 1nF = 1000pF, and 1µF = 1000nF.
Metalized PPC capacitor are similar to the above disc capacitor comparatively but are used for very high voltage application in the range of over 230 volts.
