A capacitor is a device that stores electric potential energy and charge. Unlike batteries, capacitors do not involve chemical reactions. They merely encompass the movement of charged particles, so they can be charged and discharged very quickly. This important property gives them many useful applications.
They are used as electrical flash units in Photography, lasers, air bag sensors, radio receivers, and television receivers. Most importantly, they are used in alternating-current circuits, which play a crucial role in most household and industrial power-distribution systems.

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 would be the physical size of a 1 farad capacitor?
When used in car audio applications, a 1 farad capacitor is usually about 6" long and about 2.5-3" in diameter.
What is the application of scr?
An Silicon Controlled rectifier is most utilized in switching applications. For example: discharging a capacitor. Because a SCR stays on until a certain voltage between the collector and emitter drops bellow a certain level, the SCR will stay on when triggered until the capacitor is empty.
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.

Can you use a farad capacitor as a battery capacitor?
No. The large farad capacitors are not designed to pass a lot of current. They are intended for ultra-low current applications such as memory retention in a CMOS type device.
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 has the author James Edward Hansen written?
James Edward Hansen has written: 'A time-multiplexed switched-capacitor circuit for neural network applications' -- subject(s): Neural networks (Computer science), Switched capacitor circuits
What is the role played by a capacitor in sound system?
Capacitors are generally used in high powered automotive sound applications. The capacitor acts as a storage for power. When peak parts of a music program are played and extra power is needed to drive the amplifier and speaker, the power is drawn from the capacitor. This puts less strain on the car's battery and alternator.
What variable capacitor used for tuning radio?
In radios that aren't solid state, and use variable capacitors for tuning, the air-dielectric variable capacitor is the almost universal choice for radio frequency applications. More information on air variable capacitors is available at www.orenelliottproducts.com.

Can you use a 100 mfd in place of a 60 mfd capacitor?
Capacitor values in certain applications can be very forgiving and in others quite critical. In power filtering for example you might be able to get away with the higher value. As long as the larger capacitor has the same or higher voltage rating you can give it a shot provided you understand that by doing so either it won't work or make harm your device.
Application of capacitor?
A capacitor in its simplest form is merely two electrically conductive plates separated by an insulator from each other. As such the capacitor will block any DC voltage from passing through it, up to the electrical dielectric strength of the insulator. The capacitor will accept a DC charge and an electrical field will exist between the plates of the capacitor. The capacitor will retain this charge until it either leaks away via the high electrical resistance of the insulator, or is intentionally discharged. When an AC or varying voltage is applied to a capacitor, a varying electrical field is set up between the plates of the capacitor. This will thus pass through the capacitor, and can be seen on the opposite plate. Thus, a capacitor will pass an AC voltage. Now,as to the question, " application of Capacitor". One of the oldest and most useful of capacitor applications is filtering or smoothing the output of an AC to DC power supply. In this supply, an AC voltage is rectified by a diode into a varying DC voltage. A capacitor is placed across the output, and serves to supply voltage or "fill in" the output whenever the output voltage is less than the capacitor. The capacitor subsequently recharges on the next cycle and repeats the process. Thus, the output voltage of the power supply is smoothed out.
What are the applications of ujt?
The simplest application of a UJT is as a relaxation oscillator, which is defined as one in which a capacitor is charged gradually and then discharged rapidly.
What is dc link capacitor?
when the DC current flows through the capacitor .the leakage of the charges is in capacitor called Dc leakage capacitor .
