Study Notes
Capacitor and Capacitance
- Capacitance is the ability of a capacitor to store charge per unit voltage. The formula is C = Q/V, where C is capacitance, Q is charge, and V is voltage.
- The unit of capacitance is the Farad.
- Capacitors store electrical energy. They are also called condensers.
- Different types of capacitors exist, including ceramic, electrolytic, and tantalum.
- Ceramic capacitors are commonly used in high-frequency circuits, including decoupling and filtering applications.
- Electrolytic capacitors are used in power supplies for smoothing, energy storage, and applications requiring large capacitance.
- Tantalum capacitors are widely used in space-constrained and high-reliability applications, like mobile devices and military equipment.
- Capacitors are used in various applications, including smoothing power supplies (e.g., power adapters, audio amplifiers, and televisions), timing circuits (e.g., blinking LEDs, oscillators, and pulse generators), and other electronic devices.
