Capacitor forms by the 2 oppositely charge plates separated by minor space with dielectric medium filled in the space.
The capacitor stores energy in the form of charge and can be used as high pass filters.
The first equation that was taught for capacitor was C = Q/V where C is capacitance , V is potential difference between parallel plates and Q is the charge.
According to the above equation, we might think that capacitance depends on charge and potential difference but it is not actually true-
Capacitance depends on distance between the plates (d).
dielectric between the plates (K).
area of cross section between the plates (A).
Hence we get the equation as C = K*E0*A/D where E0 is the permittivity constant whose value is 8.85 * 10^-12.
The energy stored in the capacitor increases and decreases in a exponential manner which depends on the time constant RC. Same goes with the Charge and the Potential difference.
