A capacitor is made up of two conductive plates, which are separated by an insulating material called a dielectric. The plates are usually made out of materials like aluminium and copper, and the dielectric can be made out of materials like ceramic, plastic and paper. Capacitors can range in voltage, size and farads (F) of capacitance.
At its most simple, a capacitor can be little more than a pair of metal plates separated by air. 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 ...
Applications of Capacitors. Some typical applications of capacitors include: 1. Filtering: Electronic circuits often use capacitors to filter out unwanted signals. For example, they can remove noise and ripple from power supplies or block DC signals while allowing AC signals to pass through.

Capacitors are common electronic devices that are used to store electric charge for a variety of applications. A capacitor is usually constructed with two conducting plates (called "terminals" or "electrodes") separated by either air or an insulating material. Figure (PageIndex{1}): Two examples of capacitors.
But if you place your bar between the plates of the capacitor, normal to the plates, the magnetic field produced when the capacitor is charged or discharged will have circular field lines centred on the central axis of the capacitor and the iron will indeed tend to be magnetised with its domains magnetised to form, collectively, closed loops.
From this, it can easily be seen that a larger ε leads to greater charge stored and thus greater capacitance. Dielectric materials used for capacitors are also chosen such that they are resistant to ionisation. This allows the capacitor to operate at higher voltages before the insulating dielectric ionises and begins to allow undesirable current.
Example 5.1: Parallel-Plate Capacitor Consider two metallic plates of equal area A separated by a distance d, as shown in Figure 5.2.1 below. The top plate carries a charge +Q while the bottom plate carries a charge –Q. The charging of the plates can be accomplished by means of a battery which produces a potential difference.
