A capacitor is a passive electronic component that stores electrical energy in an electric field. It consists of two conductive plates separated by an insulating material called a dielectric. When a voltage is applied across the plates, the capacitor stores energy in the form of an electric field. Capacitors are commonly used in electronic circuits for filtering, smoothing, timing, and energy storage purposes.

Definition:
A capacitor is a passive electrical component that stores electrical energy in an electric field.
Construction:
A capacitor typically consists of two conductive plates separated by an insulating material called a dielectric.
Operation:
When a voltage is applied across the capacitor, positive charges accumulate on one plate and an equal number of negative charges accumulate on the other plate. This creates an electric field between the plates, storing electrical energy.
Capacitance:
The capacitance (C) of a capacitor is a measure of its ability to store charge and is defined as the ratio of the charge stored on the plates to the potential difference (voltage) across the capacitor. The unit of capacitance is the Farad (F).
Formula:
```
C = Q / V
```
Where:
- C is capacitance in Farads
- Q is the charge stored in Coulombs
- V is the potential difference in Volts
Types of Capacitors:
There are various types of capacitors, including:
- Ceramic capacitors
- Electrolytic capacitors
- Film capacitors
- Tantalum capacitors
- Supercapacitors
Applications:
Capacitors are widely used in electronic circuits for:
- Energy storage and release
- Filtering out unwanted frequencies
- Smoothing voltage fluctuations
- Timing and phase shifting
- Resonant circuits
Properties of Capacitors:
- Energy Storage: Capacitors can store electrical energy in an electric field.
- Polarity: Some capacitors have a polarity (+ and -) and must be connected correctly to avoid damage.
- ESR (Equivalent Series Resistance): Capacitors have some resistance, which can limit their performance.
- Inductance: Capacitors can also exhibit some inductance, especially at high frequencies.
Symbols:
In electrical schematics, capacitors are typically represented by two parallel lines (||) with a small gap between them. Polarized capacitors have a + and - sign on the symbol.
