In this article, we will explore the primary functions of capacitors and how they contribute to the operation of electronic circuits. One of the most fundamental functions of a capacitor is its ability to store electrical energy. A capacitor consists of two conductive plates separated by an insulating material called a dielectric.
Capacitors are connected in parallel with the power circuits of most electronic devices and larger systems (such as factories) to shunt away and conceal current fluctuations from the primary power source to provide a "clean" power supply for signal or control circuits.
Like other electrical elements, the capacitor can be used both in circuits that process signals and circuits that process energy (in some cases, there is no clear boundary between the two types). Here are the most popular of them. In most electronic circuits, the electrical quantities voltage and current represent signals.
In electrical engineering, a capacitor is a device that stores electrical energy by accumulating electric charges on two closely spaced surfaces that are insulated from each other. The capacitor was originally known as the condenser, a term still encountered in a few compound names, such as the condenser microphone.
Here is an intuitive explanation of this phenomenon. As it charges, the capacitor tries to reach the voltage of the input AC source to neutralize it... but the input source does not stop changing its voltage. Figuratively speaking, the input source "runs" and the capacitor tries to reach it.
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.
