FAQs
- What is the difference between an electrolytic capacitor and a ceramic capacitor? Electrolytic capacitors have a much higher capacitance value than ceramic capacitors but are polarized and have a lower voltage rating.
- Can I use a higher voltage-rated capacitor in my circuit? Yes, you can use a higher voltage-rated capacitor, but it is not recommended to use a lower voltage-rated capacitor as it may lead to failure.
- How do I discharge an electrolytic capacitor? To discharge an electrolytic capacitor, connect a resistor across its terminals. The resistor should have a value of at least 1 kΩ to limit the discharge current.
