Figure 5.1.1 Basic configuration of a capacitor. In the uncharged state, the charge on either one of the conductors in the capacitor is zero. During the charging process, a charge Q is moved from one conductor to the other one, giving one conductor a charge + Q , and the other one a charge − Q .
Figure 5.3.1 Charging a capacitor. The connection results in sharing the charges between the terminals and the plates. For example, the plate that is connected to the (positive) negative terminal will acquire some (positive) negative charge.
Note that whether charged or uncharged, the net charge on the capacitor as a whole is zero. The simplest example of a capacitor consists of two conducting plates of area A , which are parallel to each other, and separated by a distance d, as shown in Figure 5.1.2.
Capacitance of an insulated conductor In a finite system of charged conductors, the algebraic sum of the charges from the system can be zero or different to zero.
In a capacitor the capacitance is deliberately localized within a relatively small volume, but in extended conductors, such as coaxial cables or transmission lines used to convey electric currents over large distances, the capacitance is distributed continuously and is an important factor in any electric phenomena which occur.
Effectively, the capacitance of conductor A kept to the potential V0, in the presence of conductor B earth connected ( ), increased carrying the charge: Then the capacitance of a conductor placed in the vicinity of another grounded conductor is bigger than the capacitance of insulated conductor .
