2 天之前· Capacitors are physical objects typically composed of two electrical conductors that store energy in the electric field between the conductors. Capacitors are characterized by how much charge and therefore how much electrical energy they are able to store at a fixed voltage.

Figure below shows the architecture of multiple plate capacitor in which four capacitors are fited in one architecture. In this type of capacitor two plates are connected together to form the metal plate 1 and three plates are connected together to form the metal plate 2. The metal plates are connected to form the elecrodes of the capacitor.
The capacitors ability to store this electrical charge ( Q ) between its plates is proportional to the applied voltage, V for a capacitor of known capacitance in Farads. Note that capacitance C is ALWAYS positive and never negative. The greater the applied voltage the greater will be the charge stored on the plates of the capacitor.
The capacitance C of a parallel plate capacitor is defined as the ratio of the charge Q on each plate to the voltage V across the plates: The capacitance C depends on the geometry of the plates and the dielectric material between them. For a parallel plate capacitor with air or vacuum between the plates, the capacitance C is given by:
The process of storing electrical energy in the form of electrostatic field when the capacitor is connected to a source of electrical energy is known as charging of capacitor. This stored energy in the electrostatic field can be delivered to the circuit at a later point of time.
The conductive metal plates of a capacitor can be either square, circular or rectangular, or they can be of a cylindrical or spherical shape with the general shape, size and construction of a parallel plate capacitor depending on its application and voltage rating.
A good analogy is if we had a pipe pouring water into a tank, with the tank's level continuing to rise. This process of depositing charge on the plates is referred to as charging the capacitor. For example, considering the circuit in Figure 8.2.13 , we see a current source feeding a single capacitor.

The capacitance C of a parallel plate capacitor with plates each having cross sectional area A, separated by a distance d is given by C = d ϵ 0 A, where ϵ 0 is the permittivity of free space with value 8.85 × 1 0 − 12 F m − 1. This equation assumes that the distance between the plates is much smaller than the size of the plates themselves.
The flow of electrons onto the plates is known as the capacitors Charging Current which continues to flow until the voltage across both plates (and hence the capacitor) is equal to the applied voltage Vc. At this point the capacitor is said to be "fully charged" with electrons.

Capacitance is the measured value of the ability of a capacitor to store an electric charge.

Thus this amount of mechanical work, plus an equal amount of energy from the capacitor, has gone into recharging the battery. Expressed otherwise, the work done in separating the plates equals the work required to charge the battery minus the decrease in energy stored by the capacitor.
