Can you use a 25 microfarad 370 volts capacitor in place of a 30 microfarad 370 volt capacitor?

Not a good idea, without knowing more about the circuit in which it's installed.
Presumably, the 440v capacitor was selected because its max voltage rating (440v) is
higher than the instantaneous voltage to be expected at that point in the circuit. By that
criterion, the voltage at that point in the circuit may exceed 370 volts, and your proposed
replacement component won't hold it.

If a single phase 240 Volt ac is applied to a full wave bridge rectifier. what will be the resultant dc voltage?
A: the rms value will be169 volts add a capacitor and no load 240 volts and the average will be 153 volts
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 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.
Is it safe to run a 220 volt AC to 12 volt DC step down transformer in a 110 volt outlet and will it transform it to 6 volts or will it run at 12 volts?
Since there is an AC to DC converter in there, it's hard to say. If it's a basic transformer to rectifier to capacitor design it will put out 6 volts. If it is a transformer to a voltage regulator it's hard to say what will happen. Certainly the drive voltage to the regularor will be cut in half. It may or may not run, but won't be able to run at 12 volts because there won't be any 12 volts to drive the regulator. (There will only be 6 volts.) If it is a switcher it may work fine or it may do nothing.
Can you replace 2200 uf 24 volt capacitor with a 2200 uf 16 volt capacitor?
NO dont do it if you devalue a capacitors voltage parameter what will it do when it is face to face with 20V ? The voltage will destroy the thing. Remember it is OK for you to use a higher voltage parameter for a capacitor but never lower
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
What does micro farads measure?
A microfarad measures electrical capacitance. A farad can be defined as the charge in coulombs, which is 1 ampere per second, that a capacitor will accept for the potential across it to charge one volt. A microfarad is equal to one millionth of a farad.
What is the Charge of 001 micro farad and 1 kilo vault?
Farad = Coloumb / Volt; solving for Coloumb, you get Coloumb = Farad x Volt. Just plug in the numbers - 1 microfarad is a millionth farad; 0.001 microfarad - if that is what you mean - is 0.000000001 Farad; wherease 1 KV = 1000 Volts.
Can you change a 470 microfarad 16 volts capacitor with a 470 microfarad 35 volts?
C=Q/V12 where Q/ V12 is the Charge per Potential Difference between the plates of the capacitor. If you solve for Q, you see that the charge is proportional to this potential difference. You are likely to surpass your load requirements by increasing the charge/discharge amplitude with the 35 volt cap. In other words, your cap will charge up to 35 volts and then discharge that 35 volts onto your load that was set at resonance to operate with 16 volts discharging. Any separation of circuits using this cap would probably fry something on one side or the other over time. Hope this helps.

Is a 50 volt 68uf capacitor the same as a 50 volt 680nf capacitor?
No they are not equal680nf = 0.68uf
Volts are measured in?
A volt is a volt is a volt.
Measure in volts?
A volt is a volt is a volt.
What is the role of a capacitor at the non-inverting input of an op-amp?
The capacitor blocks the DC portion of the signal and therefore only the AC portion is amplified. i.e if the signal applied exists at a 2 Volt level for instance, after the capacitor the 2 Volts will be trimmed off.
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......
