1. Compressor
2.A fan
3.A gas, like freon, which vapourises @ a temp lower than room temp
4.The tubing/Piping
An AC is a heat transfer operation.The gas(in the form of a liquid) travels through the piping and it evaporates very quickly cooling the tube.The fan blows air across the tubes into the room, now to turn back the evaporated gas into a liquid so that it can be evaporated again, it is led into the compressor, the compressor is basically a mechanical component, which squeezes the gas back into liquid so that it can be evaporated again, this happens continously, and during compression, a lot of heat is generated, which is thrown into the outside atmosphere.This is the basic working of any refrigating device.

∙ 12y agoA capacitor will charge and discharge according to the polarity applied to its plates, thus allowing alternating currents to pass through it whilst still blocking any flow of direct current.
Passing ac signal currents between successive stages of a radio receiver or amplifier is a very good example of a common application of this ability of capacitors to pass ac.

∙ 11y agoIn practice, sometimes an inadequately rated capacitor is connected to AC --
A: Nothing if the capacitor is non polarized and the right voltage rating. It will eventually blow up if the capacitor is polarized since AC contains positive and negative voltage
In practice, a properly rated capacitor (non-polarized, rated to handle voltages larger than any it will actually see) will act pretty close to an ideal capacitor -- the small amount of energy lost in its parasitic equivalent series resistance is usually insignificant.
In theory, when an ideal capacitor is connected to an AC circuit,
the capacitor will alternate between charging and discharging.
In theory, all the energy that flows into the capacitor during any one part of the cycle will be entirely released back into the rest of the circuit during some other part of the cycle.
The RMS flow of electrons will be proportional to the capacity of the capacitor and also proportional to the AC frequency and AC amplitude.
Properly-rated capacitors are used in AC circuits for a variety of purposes --
motor start capacitors, power factor correction, to absorb unwanted high-frequency energy, to transfer desired audio signals from one place to another while blocking unwanted low-frequency signals and unwanted "DC" offsets, etc.

∙ 9y agoNo. Capacitors store DC voltage. (Technically, charge) Plus, they store voltage, not current, so the question is invalid. You need a rectifier diode to convert AC to DC before attempting to charge a capacitor.
<><><><><>
Yes, the capacitor is charged to the maximum at that part of the cycle where the current is zero, which happens when the voltage across the capacitor is at its maximum.
<<>>
Absolutely charges and discharges the net result is zero. However, if the capacitor is polarized, such as being an electrolytic capacitor, or even if the capacitor is non-polarized but of the right value, it is possible that imposition of an AC source could cause it to explode. You need to look at the circuit design carefully before you consider doing something like this.

∙ 12y agoA capacitor will oppose the flow of alternating current, due to its capacitive reactance, (symbol: Xc) which is measured in ohms.
Capacitive-reactance is directly proportional to the capacitance (C) of the capacitor and the frequency (f) of the supply voltage. So, at higher frequencies, for example, the capacitor's capacitive reactance will be higher.
The total opposition of a typical capacitive circuit to the flow of AC current, is called impedance and this is the vector-sum of the circuit's resistance (all circuits will have some degree of resistance) and capacitive reactance.

What is the difference between electrolytic capacitors and normal capacitors?
because normal capacitors does not have any polaririties.
Where are capacitors located?
Capacitors are generally located in Electrical & Electronic Equipments..
Is a capacitor used to change an AC voltage to a lower or higher value?
Yes.... capacitors offer impedance to flow of ac current.. But since the value of impedance is inversly proportional to the frequency of source therefore the impedance offered generally is much lesser than in case of dc current
What are the different types of capacitors?
Ceramic capacitors, film capacitors, multi-layers ceramic capacitors, electrolytic capacitors, mica capacitors, super capacitors, etc. -- We're JYH HSU(JEC) Electronics Ltd (or Dongguan Zhixu Electronic Co., Ltd.), an electronic components manufacturer.

How do vfd's change the AC to dc current and back into AC?
Variable frequency drives use a rectifier to "chop off" the top part of the ac wave, then use capacitors to "fill in" the gaps in the voltage, making a "near dc" power. They use IGBTs, a fancy term for a high speed, high current transistor, or electronic switch, to pulse the "near dc" power out to the motor, in a pattern that appears like ac to the motor.
What is the cause of Hum in AC Capacitors?
Hum is caused in (low frequency) AC capacitors by electrostatic forces between the capacitor's plates, causing them to vibrate.
Do capacitors really only work in ac alternating current?
Not only for AC. Some applications use capacitors to hold a steady charge for periods of time.
How only capacitors can give smooth ac voltage waveform when used in ac circuits?
Capacitors resist a change in voltage, inversely proportional to their capacitance. As a result, transients in the AC line tend to be filtered out.
Why do you use a dc capacitor in table fans while an ac capacitor in a ceiling fan?
there is no separate capacitors for AC and DC. All capacitors are same. Electrolytic capacitors are manufactured by creating a die-electric by chemical etching or electroplating on one plate. Such capacitors when connected in AC circuit dislodges the die-electric material and thus results in short circuit between the two parallel plates of the capacitor. For AC circuits only non-electrolytic capacitors should be used. The common type is oil impregnated paper capacitor.
Does a capacitor block ac current dc current or both?
No you can't use DC capacitors in Ac because in DC current , the current flows directly while in AC current, the current flows curved zig-zag. Thus Dc equipment can't mingle with AC as they need Direct flow. So DC capacitors can't be used for AC current...................AnswerMost capacitors will operate on either DC or AC. The exception is the polarised-type capacitor, which is designed to operate with a DC or an appropriately-biased supply.Often, a capacitor's rated voltages is specified in terms of DC -for example, '100 V (DC)', so care must be exercised if it is to be used with AC. This is because we always measure AC voltages as root-mean-square (rms) values, not as peak values. For example, '100 V (AC)' actually peaks at 141 V*. So, applying 100 V (AC) to a capacitor rated at 100 V (DC) may cause its dielectric to fail. In this example, the maximum allowable AC voltage must be 70.7 V, which peaks at 100 V.(*To explain: Vrms = 0.707 Vmax )
Why capacitor is use in ac machines?
Capacitors are used in ac machines to assist the field during starting.
Can you explain why oil filled capacitors must be used for capacitor run motors instead of the more economical ac electrolytic types?
Electrolytic capacitors cannot be used on an AC (alternating current) system.
Which type of a capacitor is used for power factor correction?
A.C capacitorAnswerGenerally speaking power-factor capacitors are oil-impregnated paper capacitors -i.e. capacitors whose dielectric is manufactured from oil-impregnated paper. Power-factor capacitors are rated in reactive volt amperes, rather than in farads.There is no such thing as an 'AC capacitor', as all capacitors (other than polarised capacitor) can operate on either AC or DC.
Why capacitor is not used in ac circuit?
On the contrary, capacitors ARE used in a.c. circuits.
Did capacitor allow change in current?
capacitors allow ac current to flow.
For higher frequency response which type of capacitor is used?
Probably vacuum ac capacitors.
How do you use a diode to charge your saltwater capacitors with ac voltage?
Simply include the diode in one of the AC supply lines to your capacitor. (not sure what a salt water capacitor is) but, all capacitors only store charge, which is discharged as a DC current.
