1. What is the difference between ceramic capacitors and electrolytic capacitors?

Polarity: Ceramic capacitors are non-polar, while electrolytic capacitors are polar.
Capacity range: Electrolytic capacitors generally offer larger capacitance values.
Stability: Ceramic capacitors are more stable, especially when the temperature changes.
Lifespan: Ceramic capacitors have a longer lifespan because there is no liquid electrolyte to dry out.
2. Does the voltage of ceramic capacitors matter?

Voltage ratings are critical to ensure safe operation. Using a capacitor below the rated voltage may cause premature failure; using a capacitor above the rated voltage may cause immediate damage.
3. Do ceramic capacitors degrade over time?

The capacitance value of ceramic capacitors may decrease slightly over time and environmental factors, but this is usually a slow process.
4. Which side of a ceramic capacitor is the positive side?

Ceramic capacitors are non-polarized, so there is no positive or negative side.
