Capacitors are used in many different ways.
Here are a few instances where they are used:
There are several types of capacitors. One source for variable capacitors is:

The type of dielectric most often used in variable capacitors is air. Also, trimmer capacitors often use mica.
Usually commutating Capacitors are used in bistable multivibrators. To change the states of two transistors in bistable MVs, a trigger is applied. But due to the capacitance at base of transistor it takes sometime (delay) to change the state. To overcome this problem Commutating capacitors are used. So these are also known as Speed up capacitors or Transpose Capacitors as they speed up the operation.
Capacitors are rated in Microfarads
There is no coupled capacitor in existence that i know. Capacitors can be used to couple or decouple a signal
It is a rating that is used to size capacitors in microfarad. MFD is an acronym for the word microfarad.
The capacitors used in table fans is to start its induction motor.
Film capacitors cannot be replaced with ceramic or mica capacitors if used for analog signal processing. However, mica capacitors can be replaced with ceramic capacitors in general.
The type of dielectric most often used in variable capacitors is air. Also, trimmer capacitors often use mica.
Capacitors can be used to decrease the inductance of power lines (series compensation), and for voltage support (capacitors are put in parallel with the system).
c1 and c2 capacitors with crystal eliminates the Harmonics(Unwanted frequencies) .
.Capacitors are widely used in electronic circuits for blocking direct current while allowing alternating current to pass. In analog filter networks, they smooth the output of power supplies..Capacitors are used in virtually every area of electronics, and they perform a variety of different tasks. Some capacitors are used for coupling, others for decoupling, while others may be used in filters, and some may be used for power supply smoothing. Again some capacitors will be used in low frequency circuits, and others in high frequency circuits.
Fire alarm system may be having some electronic devices and cards, in which some capacitors are used. Capacitors are part of any electronic cards.
Ultra capacitors are also called "super capacitors." They are used in myriad electronic circuits and in electric and hybrid cars.
On the contrary, capacitors ARE used in a.c. circuits.
Capacitors are circuit devices for storing electric energy. Variable capacitors are mainly used in filter circuits and power supplies. They are used in a variety of appliances.
