reverse biased PN junction
MOS capacitors are more common
A capacitor that does not have a designated + and - side. Electrolytic capacitors are usually polarized. Ceramic capacitors are not.

A small capacitor can be part of an integrated circuit.
Capacitors are rated in Microfarads
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.
There is no coupled capacitor in existence that i know. Capacitors can be used to couple or decouple a signal
Capacitors come in various sizes, your question is to non specific (capacitor for WHAT) for a detailed answer.
The main role of dielectrics in capacitors is to increase the value of capacitance of the capacitor.
A mica capacitor is simply one that uses the mineral mica as the dielectric or insulator between plates.
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.
variable capacitors are those capacitors which can be intially or randomly canged by the user for example radio tunning.whereas fixed capacitors are those whose value is fixed and can't be changed. sohaib
