Electrolytic capacitor are used in dc power supplies to filter ac ripple .
The rectifier turns ac in to pulsating dc and with a capacitor across the output it holds a charge and so pulsating dc never goes down to zero..

An electrolytic capacitor acts as a charge reservoir in most circuits. In power supplies it provides a low-impedance source of current when there is a sudden increased demand, or is used to reduce ripple voltage. Minimizing ripple voltage in the power supply is of great importance in analog electronic circuits, such as audio amplifiers, because the ripple can be heard in the sound signal as an annoying "hum".
Electrolytic capacitors can also be used as timing elements in conjunction with a resistor network, producing time delay signals or pulse trains of a given frequency. The popular 555 family of integrated circuit timers can use them in this fashion.
The same thing as any other capacitor does (i.e. oppose changes in the voltage across it) except:
A capacitor stores charge when being supplied with a voltage and releases it when put into a circuit without one.

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.
The electrolytic capacitor can only have voltage across it in one direction. Failure to comply will result in catastrophic destruction of the 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.

An electrolytic capacitor uses an electrolyte (ions in a solution) to store charges.

Electrolytic capacitors look like little batteries. Any capacitor that looks like this will be electrolytic.Another AnswerElectrolytic capacitors are polarised, so their terminals are marked with positive and negative symbols.
