Charging and Discharging: The capacitor charges when connected to a voltage source and discharges through a load when the source is removed. Capacitor in a DC Circuit: In a DC circuit, a capacitor initially allows current flow but eventually stops it once fully charged.
The ability of the capacitor to store charges is known as capacitance. Consider the following circuit, which shows the working principle of a parallel plate capacitor with a dielectric between them. Apply the voltage V as shown in the circuit, with plate 1 being positive and plate 2 being negative. An electric field appears across the capacitor.
Capacitor Definition: A capacitor is defined as a device with two parallel plates separated by a dielectric, used to store electrical energy. Working Principle of a Capacitor: A capacitor accumulates charge on its plates when connected to a voltage source, creating an electric field between the plates.
If this simple device is connected to a DC voltage source, as shown in Figure 8.2.1 , negative charge will build up on the bottom plate while positive charge builds up on the top plate. This process will continue until the voltage across the capacitor is equal to that of the voltage source.
The capacitor may be modeled as two conducting plates separated by a dielectric as shown on Figure 2. When a voltage v is applied across the plates, a charge +q accumulates on one plate and a charge –q on the other. Figure 2. Capacitor model capacitor plates i = dq . And thus we have, dt
As this constitutes an open circuit, DC current will not flow through a capacitor. If this simple device is connected to a DC voltage source, as shown in Figure 8.2.1 , negative charge will build up on the bottom plate while positive charge builds up on the top plate.
