Its primary function is to store electrical energy and release it when needed. Capacitors are widely used in electronic devices, power systems, and communication networks. In this article, we will explore the purpose of a capacitor in a circuit and how it contributes to the overall functionality of electrical systems.
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.
Capacitors are passive electronic components that store and release electrical energy. They consist of two conductive plates separated by an insulating material known as a dielectric. When a voltage is applied across the plates, an electric field forms, allowing the capacitor to store energy in the form of an electrostatic field.
When a sudden voltage surge occurs, a capacitor can absorb the excess energy, preventing it from reaching sensitive components and causing harm. This protective function is often utilized in power supply circuits, where capacitors are placed across the power rails to suppress voltage spikes and transients.
The capacitors act as a local reserve for the DC power source, and bypass AC currents from the power supply. This is used in car audio applications, when a stiffening capacitor compensates for the inductance and resistance of the leads to the lead–acid car battery. In electric power distribution, capacitors are used for power-factor correction.
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.

Capacitors are ubiquitous in electronic circuits, where they serve various purposes such as filtering, coupling, and timing. They stabilize voltage levels, filter out noise, and facilitate signal processing in devices ranging from smartphones to computers.
A capacitor is an electrical component which stores and releases electricity in a circuit, much like a rechargeable battery does. However, a capacitor stores potential energy in an electrical field, whereas batteries accumulate energy in the form of a chemical energy, and then convert this into an electrical energy. A capacitor will only pass ...

Inside the battery, chemical reactions produce electrons on one terminal and the other terminal absorbs them when you create a circuit. A capacitor is much simpler than a battery, as it can''t produce new electrons — it only stores them. A capacitor is so-called because it has the "capacity" to store energy.

A capacitor can store electric energy when disconnected from its charging circuit, so it can be used like a temporary battery, or like other types of rechargeable energy storage system. Capacitors are commonly used in electronic devices to maintain power supply while batteries are being changed. (This prevents loss of information in volatile memory.)
Capacitors store energy in an electric field and release energy very quickly. They are useful in applications requiring rapid charge and discharge cycles. Batteries store energy chemically and release it more slowly. They are …
Capacitors store energy in an electric field and release energy very quickly. They are useful in applications requiring rapid charge and discharge cycles. Batteries store energy chemically and release it more slowly. They are useful for providing a steady supply of energy over a longer period.
There are two capacitor symbols generally used in electronics. One symbol is for polarized capacitors, and the other symbol is for non-polarized capacitors. In the diagram below, the symbol with one curved plate represents …
The larger the capacitor the less ripple and the more constant the DC. When large current peaks are drawn the capacitor supplied surge energy helps the regulator not sag in output. The white and black bars on the capacitor symbol show that it is a "polar " capacitor - it only works with + and - on the selected ends.
You see these kind of filters ( common mode choke with capacitors to ground and between the power lines ) also on switching power supplies like computer power supplies. Their purpose is not filtering noise coming in but preventing your device injecting noise into the mains. Switching power supplies are notoriously noisy and they have to add ...

So, the so-called "coupling capacitor" serves as a floating voltage source connected in series to a varying voltage source with the purpose to transfer its voltage variations. For example, in a common-base stage (Fig. 2, 3 and 4), the input coupling capacitor Ce "shifts up" the input voltage variations and the output coupling capacitor Cc "shifts down" the output …
