-
1. Is ceramic capacitor AC or DC?
Ceramic capacitors can be used in both AC and DC circuits. They have no polarity, so they can be installed at will.
-
2. How do I know if my ceramic capacitor is bad?
Visual inspection: Check for cracks, bulges, or other physical damage.
Multimeter test: Measure the capacitance value to see if it is close to the nominal value, and check for shorts or opens. -
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. Can ceramic capacitors be used for audio?
Ceramic capacitors can be used in audio circuits, but care needs to be taken to select the right type to avoid introducing unnecessary noise or distortion.
