A capacitor is an electrical component that stores and releases electrical energy in a circuit. It consists of two conductive plates separated by an insulating material called a dielectric (such as air, plastic, or ceramic).
Here's how it works:
Capacitors are used in many electronic devices for tasks like:
Capacitance, which is the ability of a capacitor to store charge, is measured in farads (F). The larger the capacitor, the more charge it can store.
Here's how it works:
- When a voltage is applied across the plates, electrical charge builds up on the plates, with one plate becoming positively charged and the other negatively charged.
- The capacitor stores this energy as an electric field between the plates.
- When the capacitor is connected to a circuit, it can release the stored energy quickly, which is useful in various applications.
Capacitors are used in many electronic devices for tasks like:
- Filtering (to smooth out electrical signals)
- Energy storage (in power supplies)
- Timing circuits (in oscillators)
