🧠 How Capacitors Work
Store electrical charge between two plates separated by a dielectric.
Smooth voltage fluctuations in power supplies.
Filter noise in audio or digital circuits.
Release stored energy for short bursts in motors or LEDs.
💡 Practical Tips
Always select a voltage rating higher than your circuit voltage.
Use electrolytic capacitors for bulk storage and smoothing.
Use film or ceramic capacitors for high-frequency filtering or timing.
Supercapacitors are ideal for energy storage or backup power, but check polarity carefully.
For AC applications, choose non-polarized types to prevent damage.
