Electric Capacitor: Essential Energy Storage for Electronics

An electric capacitor is a passive electronic component used to store and release electrical energy in a circuit. It consists of two conductive plates separated by a dielectric material, allowing it to temporarily hold an electric charge. Capacitors are crucial in power supplies, signal processing, motor drives, and modern electronics.

🔹 Key Features of Capacitors

✅ Energy Storage & Release – Helps regulate voltage and power delivery.
✅ High-Speed Charge & Discharge – Essential for high-frequency applications.
✅ Filtering & Smoothing – Reduces voltage fluctuations in power circuits.
✅ Signal Coupling & Decoupling – Allows AC signals to pass while blocking DC.
✅ Long Lifespan & High Reliability – Used in critical electronic and industrial systems.
