What Are Capacitors?

A capacitor is a passive electronic component that stores and releases electrical energy. It consists of two conductive plates separated by an insulating material called a dielectric. When voltage is applied, electric charges accumulate on the plates, creating an electric field and storing energy.

Key Functions of Capacitors:

• Energy Storage: Store and release energy quickly when needed.
• Filtering: Remove noise from signals in power supplies and audio systems.
• Coupling/Decoupling: Isolate AC signals while blocking DC or stabilize voltage in circuits.
• Timing Circuits: Work with resistors to create time delays.

How Capacitors Work

Capacitance, measured in Farads (F), determines how much charge a capacitor can store. This value depends on:

1. The surface area of the plates.
2. The distance between the plates.
3. The type of dielectric material.

The relationship is expressed as:
Q=C×V
Where:

• Q is the charge stored (in Coulombs).
• C is the capacitance (in Farads).
• V is the voltage applied (in Volts).
