Typically the markings on a capacitor may give the figures like 22 and 6V. This indicates a 22µF capacitor with a maximum voltage of 6V. Ceramic capacitor markings: Ceramic capacitors are generally smaller than types like electrolytic capacitors and therefore the markings need to be more concise. A variety of schemes may be used.
For example, a ceramic disc capacitor with the markings 103 would indicate 10 and 3 zero''s in pico-farads which is equivalent to 10,000 pF or 10nF. Likewise, the digits 104 would indicate 10 and 4 zero''s in pico-farads which is equivalent to 100,000 pF or 100nF and so on.
Let''s examine some typical capacitor markings. The image above is of an electrolytic capacitor marked with "100μF," meaning it has a capacitance of 100 microfarads (the μ prefix indicates 10 −6 ).

The amount of electrical energy stored in the capacitor is known as its capacitance. The Capacitance of a capacitor is directly proportional to the capacity of the capacitor for storing charge. For example; the bigger the tank the more water it can store similarly the bigger the capacitance, the more charge it can store. How to Increase Capacitance
