Customer Service2 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. Quantitatively, the energy stored at a fixed voltage is captured by a quantity called capacitance

Let the rod have a charge Q and the shell a charge –Q. There is no electric field inside the rod and the charge Q is located on its surface. To find the capacitance first we need the expression of the electric field between the two conductors which can be found using the Gauss’ law.
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. Experiments show that the amount of charge Q stored in a capacitor is linearly proportional to ∆ V , the electric potential difference between the plates. Thus, we may write
• A capacitor is a device that stores electric charge and potential energy. The capacitance C of a capacitor is the ratio of the charge stored on the capacitor plates to the the potential difference between them: (parallel) This is equal to the amount of energy stored in the capacitor.
