there are infinite circuits that use capacitors however some common ones include:
frequency filters: the capacitor is used in conjunction with a resistor to only allow either high or low frequencies to pass through the circuit.
Time delay circuits: such as the intermittent setting on windscreen wippers. a capacitor is charged up and when it reaches a high enough voltage it is able to close a relay switch and start the wiper blades.
Transient circuits: similar to above in usage, but is done by creating a "ringing" in the circuit. much like hitting a bell. once the ringing becomes quiet enough the circuit becomes active. this is used in automatic roller doors to keep the light on after the door has closed for 30 seconds or so.
Voltage regulators: to maintain a steady voltage capacitors are used to "absorb" sudden spikes and troughs in the voltage input. much like suspension in a car absorbs vibrations when it hits a pothole.

How capacitors are arranged?
Capacitors are one of the standard components in electronic circuits. Moreover, complicated combinations of capacitors often occur in practical circuits. It is, therefore, useful to have a set of rules for finding the equivalent capacitance of some general arrangement of capacitors. It turns out that we can always find the equivalent capacitance by repeated application oftwosimple rules. These rules related to capacitors connected in series and in parallel.
What is the function of input and output coupling capacitors CC1 and CC2?
We don't know much about the circuit these capacitors are in, but they are coupling capacitors. Coupling capacitors isolate DC between stages or circuits, and they couple AC between those circuits or stages. Only the signal gets in and goes out. The DC the stage operates on is isolated from stage to stage.
What is the design procedure for clamping circuits?
Clamping circuits use diodes and capacitors. First, the first circuit must be set up, then a?æsine wave should be input into it. The input and output should be observed and adjusted as necessary; then, the process should be repeated for the other circuits.
Where are capacitors used?
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 biasin power supplies to minimize AC ripple on the DC waveformin timer circuits to create specific patterns and frequencieswith integrated circuits to prevent ripple from the power supply from reaching the ICin analog computation machines for creating integrators and differentiatorsin high voltage AC systems to "add VARs" to the system.
Why you use capacitive filters in rectifier circuits?
In any rectifiers circuits the purpose is to get a DC voltage by giving AC voltage as input.by connecting capacitors parallally in the circuit it is possible to get pure DC output.capacitor filter only eliminates the ac quantities remainimg in the output waveforms.so that finally we get pure DC for further aplications in electronics circuits.
What use of c in circuits?
C = capacitors. Capcitors can be used to store voltages so that they become voltage sources, or they can be used in mixed A/D circuits as timers, attenuators, filters, etc.
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 RC circuit is preferred over RL circuit in waveshaping?
There is no true advantage of RC circuits over RL circuits, as they perform different functions. RC circuits contain resistors and capacitors, while RL circuits contain resistors and inductors.
Why capacitor is not used in ac circuit?
On the contrary, capacitors ARE used in a.c. circuits.

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.
Capacitors in a tv?
what about them? You didn't ask a question so we can't answer it
Should the capacitors used in electronic circuits have a minimum voltage rating of 25 volts?
Capacitors used in electronic circuits need not have a minimum voltage rating of 25 volts. Electronic circuits powered by batteries at 12 volts and below should work fine with capacitors rated at 15 volts.
Most commonly used capacitors in electronics circuits are made up of?
pass AC voltages.
