Yes. Electrolytic capacitors are polarized.
Capacitors with positive and negative poles generally have positive and negative marks. Generally, for capacitors with pins, the long end of the pin is the positive electrode. For cylindrical electrolytic capacitors, there will be a vertical line printed on the negative side of the capacitor. SMD capacitors generally have no positive and negative poles.

Difference between electrolytic and non-electrolytic capacitors?
Electrolytic Capacitors:1. It provides high capacitance in small volume.2. It has got polarity.3. It is not suitable for high frequencies due to losses in dielectrics.4. It is generally available in 1-100 µF rangeNon-Electrolytic Capacitors:1. Its capacitance depends on dielctric constant of the bulk.2. It doesn't have polarity.3. It is widely used at all frequencies.4. It ranges from pico Farads to fractions of µF.
What capacitors are polarity sensitive?
While most electrolytic capacitors are the ones that have a polarity noted as minus "-" and "+" as opposed to ceramic or film capacitors, it's important to note that even electrolytic capacitors could also be labelled as "np" for non-polarized or "bp" bi-polarized, which means the same thing, that there is no plus or minus and the current can flow in both directions. Today a good quality electrolytic, most of the time, will be another color to depict this such as green for example, whereas in older circuits they could sometimes look identical but just be missing the little "-" indicator. So, you need to pay attention to this little detail on older boards when replacing a capacitor.
Which two types of capacitors are polarized?
Electrolytic and tantalum
What kind of capacitor is using in electric fans is it electrolytic?
Most fan capacitors are electrolytic and non-polariced. The trick is that two electrolytic capacitors are connented together in a single package. The negative terminals are connected together internally and the positive terminals form the external leads. For more information, visit books.google.co.ke.
Why should electrolytic capacitors not to be used in AC circuits?
Electrolytic caps are polorized and are used for filtering and will charge up to a DC value as in power supplies.
Is capacitor polarity sensitive?
Some capacitors are polarity sensitive; some are not. It depends on the design. Electrolytic capacitors, for instance, are polarity sensitive, while ceramic disc capacitors are not. You can generally tell, if the capacitor is marked with polarity signs, such as + and -, if it is or not.
Are capacitors polarity sensitive?
The capacitors those are polarity sensitive are called electrolytic and tantalum capacitors. These capacitors are labeled as positive and negative.
Is there any necessary to mark polarity on capacitor?
For electrolytic capacitors, yes, as ignoring their polarity can damage them.
Is there a negative and positive polarities on capacitors?
Electrolytic and tantalum capacitors both have polarity.

What type of capacitors polarity of the applied voltage must be taken care off?
Electrolytic capacitors are the type of capacitor that has to have its polarity checked when added into a circuit.See related links below.
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 capacitor burst?
Electrolytic capacitors tend to explode when connected to AC or to DC currents of the wrong polarity. The plates short out because the dielectric is maintained by a polarized field, and is then destroyed by the wrong polarity.

Difference between ceramic and electrolytic capacitors?
In ceramic capacitors the dielectric is a thin layer of ceramic and both plates are metal foil. These capacitors are unpolarized. These capacitors have negligible internal inductance or resistance.In electrolytic capacitors the dielectric is an ultra thin layer of corrosion on the surface of a metal foil plate and the other plate is an electrolyte paste. These capacitors are polarized and if connected backwards are likely to explode. These capacitors have significant internal inductance, making them bad filters of noise in the MHz range and above which requires ceramic capacitors.
What is the difference between electrolytic capacitors and normal capacitors?
because normal capacitors does not have any polaririties.
