Capacitors, along with inductors and resistors, are the three basic passive components of electronics; the function of capacitors is to store electrical energy in the form of electric field energy.
A DC voltage is applied to two metal plates that are close to each other and parallel to each other (with a dielectric between the plates); after stabilization, the metal plate connected to the positive pole of the voltage will present a certain amount of positive charge, while the metal plate connected to the negative pole of the voltage will present an equal amount of negative charge; in this way, an electrostatic field will be formed between the two metal plates, so the capacitor stores electrical energy in the form of electric field energy, and the amount of charge stored is Q.
