They have moving and fixed plates to determine the capacitance and are generally used in circuit of Transmitters and Receivers, Transistor Radios etc. The main function of a capacitor is to store electric energy in an electric field and release this energy to the circuit as and when required.
The capacitor charges and discharges cyclically. This results in an AC current flowing through the capacitor, with the capacitor acting as a reactive component that impedes the flow of AC to a degree that depends on the frequency of the AC signal. The concept of the capacitor dates back to the 18th century.
This separation of charges allows the capacitor to store electrical energy in the form of an electrostatic field. The amount of energy a capacitor can store depends on its capacitance, which is measured in farads (F). The higher the capacitance, the more energy the capacitor can store for a given voltage.
Potential Difference Maintained: The capacitor maintains a potential difference across its plates equal to the voltage of the power source. This potential difference is accessible when the capacitor is connected to another circuit element.
Basic Structure: A capacitor consists of two conductive plates separated by a dielectric material. Charge Storage Process: When voltage is applied, the plates become oppositely charged, creating an electric potential difference. Capacitance Definition: Capacitance is the ability of a capacitor to store charge per unit voltage.
The first place you might expect to see capacitors are in power supplies of all sorts as filters and for decoupling. They act as charge reservoirs – providing quick current when the load needs it. Here are two oscilloscope shots that show the effect of not having and having a capacitor across the leads of a power supply.
