Capacitor
What is a Capacitor, And What is Capacitance?
Key learnings:
- Capacitor Definition: A capacitor is a basic electronic component that stores electric charge in an electric field.
- Basic Structure: A capacitor consists of two conductive plates separated by a dielectric material.
- Charge Storage Process: When voltage is applied, the plates become oppositely charged, creating an electric potential difference.
- Capacitance Definition: Capacitance is the ability of a capacitor to store charge per unit voltage.
- Factors Influencing Capacitance: Capacitance depends on the plate area, the distance between plates, and the dielectric material’s permittivity.
What is a Capacitor?
Capacitors are one of the three basic electronic components, along with resistors and inductors, that form the foundation of an electrical circuit. In a circuit, a capacitor acts as a charge storage device. It stores electric charge when voltage is applied across it and releases the charge back into the circuit when needed.
