The voltage rating of a capacitor is the maximum amount of voltage that a capacitor can hold. Going above this rating can damage and destroy the capacitor.

Answer

Exceeding a capacitor's voltage rating can cause its dielectric to break down. A capacitor's voltage rating is generally expressed as a d.c. voltage so, if it is to be used with an a.c. system, it's necessary to know the peak value of the a.c. voltage, which is determined by dividing the a.c. (rms) voltage by 0.707.

Why is voltage rating of a capacitor important to the user?

The voltage rating of a capacitor tells the user how much voltage the capacitor can withstand. If a user exceeds this voltage, the capacitor's dielectric may be damaged and destroyed.


What does the volt on a capacitor mean?

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


Can you use a high voltage capacitor on a low voltage battery?

Yes. You just don't want to exceed the voltage rating of the capacitor.


Can you use a higher voltage rating capacitor with the same uf rating?

Yes, it will work fine. The downside is that it might cost more than one of the lower voltage rating, or that it might be physically larger. A capacitor voltage rating is a maximum, so any lower voltage is also acceptable.


By what factors is the life expectancy of a capacitor increased if the capacitor is operated at half its voltage rating?

eight


Will capacitor size increase if the voltage rating oes up?

Yes.


Which type of capacitor has the highest voltage rating?

Those with vacuum as the dielectric have.


How do you charge a capacitor?

You charge a capacitor by placing DC voltage across its terminal leads. Make sure when using a polarized capacitor to place positive voltage across the positive lead (the longer lead) and negative voltage across the negative lead. Also make sure that the voltage you charge the capacitor to doesn't exceeds its voltage rating.


Can you use a 35uf oval capacitor in place of a 45uf round?

The shape of a capacitor has no meaning to the circuit. What matters is the capacitance, the voltage rating, and the current rating. 35uf is not the same as 45uf.


Can you replace 1.7 microFarad capacitor with 2 microFarad capacitor of capacitor start motor?

It should work okay as long as voltage rating is equal to or greater than the capacitor you are replacing.


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.


What is the allowable capacitance and voltage difference when replacing a capacitor?

I depends on the application for a rate amplifier the exact value is mandatory but for filtering that can vary greatly since every cap of that type has a very large -/+ tolerance YOU may install a greater voltage breakdown but never a less then the original
