Its definition, diagram, working, specifications, applications, capacitance color coding, and types of capacitors with pictures. Capacitors an electrical or electronic component that stores electric charges.
Capacitors consist of two conductive plates, each of which hosts an opposite charge. These plates are separated by a dielectric or other form of insulator (such as ceramic, polyester, tantalum air, or polystyrene), which helps them maintain an electric charge.
The effect of the capacitor is called capacitance. The definition of capacitance is the electric charge Q divided by the voltage V, and it is represented as In coulombs, Q represents the electric charge. V is the voltage, expressed in volts, across the plates. Read Also: 25 Different Types of Electrician Tools and Their Uses
A Leyden Jar was an early example of a capacitor. Capacitors are another element used to control the flow of charge in a circuit. The name derives from their capacity to store charge, rather like a small battery. Capacitors consist of two conducting surfaces separated by an insulator; a wire lead is connected to each surface.
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.
When a capacitor is connected to a power source, electrons accumulate at one of the conductors (the negative plate), while electrons are removed from the other conductor (the positive plate). This creates a potential difference (voltage) across the plates and establishes an electric field in the dielectric material between them.
