Study Notes
Capacitance
Definition
- Capacitance is the ability of a capacitor to store electric charge.
- It is a measure of the amount of electric charge stored per unit of potential difference.
Unit
- The unit of capacitance is the Farad (F).
- 1 Farad is equivalent to 1 Coulomb per 1 Volt.
Formula
- Capacitance (C) can be calculated using the formula: C = Q / V
- Where Q is the electric charge stored and V is the potential difference.
Factors Affecting Capacitance
- The capacitance of a capacitor depends on the following factors:
- Area of the plates (A)
- Distance between the plates (d)
- Dielectric material used
- Number of plates
Types of Capacitance
- There are three types of capacitance:
- Self-capacitance: The capacitance of a single conductor or plate.
- Mutual capacitance: The capacitance between two or more conductors or plates.
- Ground capacitance: The capacitance between a conductor or plate and ground.
Importance of Capacitance
- Capacitance is a crucial parameter in electrical circuits as it determines the amount of energy stored in a capacitor.
- It plays a key role in filtering, coupling, and tuning applications.
