DevinAn electrolytic capacitor is a capacitor that is built using a special electrolyte as the insulator between the plates. By doing this, you can make the spacing very, very small and thus raise the the capacitance into the thousands of microfarads, making them especially suitable for power supply use. Unfortunately, the design only allows charge to be built up in one direction only, hence they have a designated PLUS terminal, which cannot be allowed to go negative without destroying the capacitor. Additionally, the electrolyte needs to be reformed from time to time, by imposing a charge on it and allowing it to bleed off. Normal use will suffice, but if the device sits unused for a long period of time, it can fail on first use unless reforming steps are taken.

Why electrolytic capacitor has polarity?

Does 001 farad of capacitor have polarity?
Only electrolytic capacitors (tantalum capacitors are a type of electrolytic capacitor) are polarized.0.001 farad = 1000 microfaradThis is a value that is too large for any practical capacitor except an electrolytic, so yes it will be polarized.
Why is it important consider the correct polarity of an electrolytic capacitor when using it in the circuit?
The electrolytic capacitor can only have voltage across it in one direction. Failure to comply will result in catastrophic destruction of the capacitor.
What are the examples of polarized capacitor?

What are types of capacitor?
Electrolytic capacitors are capacitors in which one or both of the plates is a non-metallic conductive surface, or in other words, an electrolyte. Electrolytic capacitors come in a variety of types including: aluminum electrolytic capacitor; tantalum; and a solid aluminum electrolytic capacitor with organic semiconductor electrolyte or OS-CON.
