What is
Capacitor:- Capacitor is a electronic device that stores electric charge.Two metal plates ,separated by an insulator constitute a
capacitor or condenser.The plates accumulate electric charge when connected to
power source.The plates are made of a conductive materials like-aluminum, silver,tantalum
etc.

How capacitor work:- A
capacitor is made of two metallic plates, with a dielectric material in between
the plates. When you apply a voltage over the plates,a capacitor works by
storing energy electrostatically in an electric field.

Principle of a capacitor:-
A capacitor works on the principle that the capacitance
of a conductor is brought near it.A
capacitor has two plates separated by a distance having equal and opposite chares.
SI Units :- SI units of capacitance is
Farads.
C= Q/V
Capacitor in series:- When
negative plates (-ve) of one capacitor connected with positive (+ve) plates of
another capacitor then we can say that capacitor are connected in series.
1/C =1/C1+1/C2+1/C3
Capacitor in parallel:-When one plate of each capacitor is
connected to the positive (+ve) terminal
of the supply mains and the another plate
of each capacitor to the negative (-ve)
terminal.
C=C1+C2+C3
