Capacitors are used in many different ways.
Here are a few instances where they are used:
- in amplifier circuits to isolate small signal circuitry from amplifier circuits' DC bias
- in power supplies to minimize AC ripple on the DC waveform
- in timer circuits to create specific patterns and frequencies
- with integrated circuits to prevent ripple from the power supply from reaching the IC
- in analog computation machines for creating integrators and differentiators
- in high voltage AC systems to "add VARs" to the system.

Which type of dielectric is used most often in variable capacitors?
The type of dielectric most often used in variable capacitors is air. Also, trimmer capacitors often use mica.
What is meant by commutation capacitor?
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.
How are capacitors rated?
Capacitors are rated in Microfarads
What is coupled capacitor?
There is no coupled capacitor in existence that i know. Capacitors can be used to couple or decouple a signal
What are mfd ratings?
It is a rating that is used to size capacitors in microfarad. MFD is an acronym for the word microfarad.
Does table fans have capacitors?
The capacitors used in table fans is to start its induction motor.
Whether film capacitors can be replaced with ceramic or mica capacitor?
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.
Which type of dielectric is used most often in variable capacitors?
The type of dielectric most often used in variable capacitors is air. Also, trimmer capacitors often use mica.
Why capacitor used in transmission line?
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).
Why Two 33pF capacitors are used with crystal oscillator?
c1 and c2 capacitors with crystal eliminates the Harmonics(Unwanted frequencies) .
What are uses capacitors?
.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.
What is the use of capacitors in fire alarm circuit?
Fire alarm system may be having some electronic devices and cards, in which some capacitors are used. Capacitors are part of any electronic cards.
What is the definition of ultracapacitator?
Ultra capacitors are also called "super capacitors." They are used in myriad electronic circuits and in electric and hybrid cars.
Why capacitor is not used in ac circuit?
On the contrary, capacitors ARE used in a.c. circuits.
What is the purpose of a variable capacitor?
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.
