the voltage number on the capacitor indicates that the capacitor can with stand to that particular voltage across it.generally during design, the value of capacitor will be selected in such a way that this voltage rating should be double than what really we get in the circuit

What type of capacitor use to stabilize a 12 volt car when the voltage drops and how to wire?
"What type of capacitor use to stabilize a 12 volt car when the voltage drops and how to wire?"
What do you mean by a 5 volt lamp?
lamp works on power of volt
What does Volt-Amp mean?
A 'volt ampere' (not 'volt amp'!) is the unit for theapparent power of a load in an a.c. circuit. It is simply the product of the supply voltage and the load current.
Would a 12 volt battery need to use a capacitor to run a 1000 or 760 watt amp?
I have a 760 watt amp powering 2 10" subs and it works fine. my brother has a 1000 watt amp powering 2 12" subs and he got a capacitor. So it really depends on what amp your looking at. if the 760w you wont need one, if the 1000w i would be safe and buy a capacitor. for the 1000w amp you would only need a 1 or 2 farad capacitor.
The air conditioning work in 230 volt why the compressor use capacitors of 370 and 440 volts if he only need mfd to start?
An AC capacitor is composed of two DC capacitors with the foil ends (-) connected together and the center ends (+) connected to the outside. There are variations to the connections. Each capacitor has to have the voltage rating required by the application -- and there are two capacitors in series in an AC capacitor. A 230V AC capacitor, depending on manufacturing design standard, may not be suitable for starting a 230V air conditioner.
Is a 50 volt 68uf capacitor the same as a 50 volt 680nf capacitor?
No they are not equal680nf = 0.68uf
Can a 440 volt capacitor be used for a 230 volt application?
No. The capacitor will short out and possibly explode. On the other hand, the 440 Volt Cap can be used in a 220 Volt circuit.
What happen if you replace a 6.3 volt capacitor with a 10 volt capacitor?
Nothing will happen, you can go over 6.3v but never under......
Why does a 230volt motor have a 110 volt capacitor?
Because the capacitor only needs to "excite" one of the two phases of the 230 volt supply in order to start the motor.

Can you change a 440 volt 12.5 uF start capacitor with a 370 volt 12.5uF run capacitor?
There are two ways to read this: you have a burned-out run capacitor on your motor and a good start capacitor in your parts box, and you have a burned-out start capacitor and a good run capacitor. If the run capacitor's bad and you want to put the higher-voltage start cap in its place, the answer is yes. This is called derating, and the only thing it does for you is increases the lifespan of the capacitor because you're not working it as hard as it can take. If the start capacitor's bad, don't do this--they used a 440-volt capacitor in there for a reason.
Why capacitor can be defined in kvar?
Capacitors designed to be used for power-factor correction are rated in reactive volt amperes, rather than in farads.The reason for this is that in order to determine the necessary correction, a load's existing reactive volt amperes is first calculated, then the reactive volt amperes of the capacitor must be determined in order to achieve the required value of power factor. In other words, the capacitance (in farads) of the capacitor is irrelevant to the calculation.
Why 440 volts running capacitor if my ac is 230 volts?
The 440 volts listed on the cap is the maximum allowable voltage the capacitor can handle. You could actually use a 370 volt cap on 230 volts. ANSWER; 230 volts AC can it actually be 644 volts peak to peak . It is 44ov because it must be rectified and sees only 324 volt peak which is withing the 440 volt capacitor handling voltage
How can be determined the rating of capacitor bank?
If you are talking about a capacitor bank used for power-factor improvement, then it is rated in reactive volt amperes (var). Otherwise, it is rated in farads (F).
Unit of capacitor is?
The SI unit of capacitance is the farad. 1 farad is 1 coulomb per volt.
What the the correct size capacitor for a three quarter horsepower 110 volt motor?
110v 40 uf
What will happen if two terminals of capacitor are shorted?
When the terminals of a capacitor are connected together, the capacitor will discharge, returning to a zero potential state. Capacitors resist voltage change, meaning that if the capacitor is in a circuit that has zero voltage potential, the capacitor will eventually achieve zero potential. If the capacitor is in a circuit that has a 5 volt potential, the capacitor will seek and attempt to maintain that 5 volt potential (provided that the capacitor is rated at 5 volts or more). In an AC circuit, the capacitor will tend to smooth out the sin wave of the current, resisting change in both directions. In a DC power supply circuit, a capacitor will tend to reduce the voltage "ripple", and if the circuit is designed properly, will provide a smooth DC voltage. Shorting the terminals of a capacitor is effectively what often happens in many circuits; it's not a problem.
