Applications of capacitors?

Answer 1

Capacitors are everywhere use in electrical and electronics.
They are used to control the power factor (in induction loads),
Start the single phase motor (split the windings 90 degree apart),
Timer controls(charging and discharging of capacitor is constant always in particular voltage, so we keep the cut off or cut on timing), frquency tuning and almost all of the DC circuits are using Capacitor for charging, keeping the potential balance and etc...

1.Energy storage:
A capacitor can store electric energy when disconnected from its charging circuit, so it can be used like a temporary battery, or like other types of rechargeable energy storage system.
2.Pulsed power and weapons:
Groups of large, specially constructed, low-inductance high-voltage capacitors (capacitor banks) are used to supply huge pulses of current for many pulsed power applications. These include electromagnetic forming, Marx generators, pulsed lasers (especially TEA lasers), pulse forming networks, radar, fusion research, and particle accelerators.
3.Power conditioning:
A 10,000 microfarad capacitor in an amplifier power supply
Reservoir capacitors are used in power supplies where they smooth the output of a full or half wave rectifier. They can also be used in charge pump circuits as the energy storage element in the generation of higher voltages than the input voltage.
4.Signal processing:
The energy stored in a capacitor can be used to represent information, either in binary form, as in DRAMs, or in analogue form, as in analog sampled filters and CCDs. Capacitors can be used in analog circuits as components of integrators or more complex filters and in negative feedback loop stabilization. Signal processing circuits also use capacitors to integrate a current signal.
5.Motor starters:
In single phase squirrel cage motors, the primary winding within the motor housing is not capable of starting a rotational motion on the rotor, but is capable of sustaining one. To start the motor, a secondary "start" winding has a series non-polarized starting capacitor to introduce a lead in the sinusoidal current. When the secondary (start) winding is placed at an angle with respect to the primary (run) winding, a rotating electric field is created. The force of the rotational field is not constant, but is sufficient to start the rotor spinning.

Answer 3

Because they block D.C., they are great RF couplers. They are also good for filtering A.C. from D.C. lines, such as power supplies, and they work well in parallel with a resistor to create a timer. It would be almost impossible to design any circuit without capacitors.

Answer 4

A basic capacitor is basically just a quick charge discharge battery, in power supplies it used to balance the wave when changing from ac to dc. In shop class we used to charge up a cap and then tos it someone yelling "think fast" when they caught it it would give them a little shock and we would all laugh. that seems the best use of a cap I can think of :)..

Answer 6

everywhere... you basically need them for everything electronic right?
