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.
AnswerExceeding 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.

∙ 11y agoCapacitors are just like batteries in that they supply different voltages in circuits, depending on the needs of the circuit, only they dishcharge much more quickly. Differing circuits have different voltage requirements, so the capacitors come in different voltage ratings.

The rated voltage of the capacitor refers to the effective value of the highest DC voltage and the highest AC voltage that can be continuously applied when working at the lowest and highest ambient temperature.
The rated voltage of the capacitor is the DC voltage that the two poles can withstand. This voltage value is generally written on the surface of the capacitor, and the prominent sign is the unit "V" with the voltage after the value. There is room for the insulation withstand voltage marked on each capacitor, which is generally 1.5 to 2 times higher than the rated voltage. This is because, in the application of capacitors, not only the withstand voltage of the two poles, but also many comprehensive factors must be considered. Therefore, in order to ensure the safety of the application, the capacitor must not exceed the rated voltage in the application.

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.
Why power rating of capacitor is reactive in nature?
A capacitor is composed of metal plates. Voltage is applied to one, which causes electrons to build up on the other. This is reactive in nature, thus a capacitor is reactive. It stores a charge, and releases this charge when the voltage decreases.
How do you increase the value of a capacitor?
A: Any additional capacitor added in parallel will effectively increase to total capacitance by that value. Note that additional capacitor added must have the same voltage rating as the other
Can you change a 35mF 425volts capacitor with a 20mf 410 volts capacitor?
Only if you are sure the voltage is less than 410 volts peak or it might fail. and- only if you are sure the reduced capacitance will not affect circuit operation. For most purposes, no, you should not do that.
Can you switch a 1800 microfarad with a 2200 microfarad capacitor?
A: I hope you mean replace. The answer is yes provided that the voltage rating is the same or more then the original.
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
Which type of capacitor has the highest voltage rating?
Those with vacuum as the dielectric have.
Will capacitor size increase if the voltage rating oes up?
Yes.
What does 200WV 470uF mean on a capacitor?
200WV is the working voltage of the capacitor. This is the value that should not be exceeded between the two terminals. 470uF is the capacitive rating of the capacitor. It means 470 micro Farads, or 0.47 Farads.
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.
When might it be necessary to use a 2 µF polyester capacitor rather than a 2 µF electrolytic capacitor?
when high voltages are present because the voltage rating of polyester (polyethylene terephthalate) capacitor is high as well as electrolytic capacitor will destroy if the voltage increases from nominal voltage and cause short circuit conditions.
