A capacitor is a circuit component that stores energy in the electric field set up between its plates.
Capacitors are named after the dielectric used to separate their plates (e.g. 'mica' capacitor), and there are lots of different types of dielectric used (too many to list), so there are a corresponding number of types of capacitor.
But you can also categorise a capacitor as being 'polarised' or 'non-polarised'; electrolytic capacitors are 'polarised', which means that they must be connected into a circuit while taking into account the polarity of their terminals.
Finally, you can categorise them as being 'fixed value' or 'variable'.

Which types of transformers used in industries?
There are many different types of transformers used in industry. They include polyphase, capacitor voltage, and resonant transformers.
What is the common application for capacitors in electric motors?
There are 2 types of capacitor including starting capacitor and running capacitor running capacitor are used to improve the power factor of motor. starting capacitor used in split phase induction motor . starting capacitor may isolate from motor,s starting winding through of centrifugal switch after getting motor 90% of it,s rated speed.
What does a disc capacitor do?
A disc capacitor does exactly the same thing that any other capacitor does, with one difference: it has the lowest value of parasitic inductance of any type of capacitor. As inductance is exactly the opposite property to capacitance, its presence in a capacitor is very undesirable in many applications and can sometimes result in circuit instability.
What is the typical tolerance for a air capacitor?
many numbers
Can you by-pass a capacitor in an electric motor?
You can not by-pass the capacitor in an electric motor. Most are capacitor-start motors which require the capacitor to be operational in order to start. If the capacitor is not working then it will need to be replaced.
Which types of transformers used in industries?
There are many different types of transformers used in industry. They include polyphase, capacitor voltage, and resonant transformers.
When was the tantalum capacitor invented?
The tantalum capacitor was produced in 1956 by D. McLean and F. Power of the United States, after which it became among the most widely used capacitor types.
What are the different types of semiconductor?
Transistor Diode Resistor Capacitor
What types of capacitors are used in fluorescent tube starters?
electrostatic capacitor
What are the types of single phase ac motor?
capacitor start motor
What is a filter capacitor?
Capacitor has many applications in electronics circuits, one of its application is in FILTERS. Mainly two types of Filters are formed with the help of capacitor namely, i)Low Pass Filter(LPF) ii)High Pass Filter(HPF) Impedance of capacitor is inversely propotional to the frequency, therefore a capacitor in series with resistor will act as Low Pass Filter. since all the high frequency are passed to ground.
What are four types of keyboard switches?
mechanical, membrane, rubber dome, and 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.
Is a power factor capacitor different from a regular capacitor?
A power factor capacitor is a power capacitor. I'm not sure what you mean by "regular". There are different types, made from different materials that have better/worse characteristics than others depending on the application. You could use any high power capacitor for power factor correction, as long as it is sized correctly for the load and voltage.
