You test it.
For electrolytic capacitors, it's sometimes (but not always) obvious simply by looking at it that there is a problem; if the capacitor bulges or is actually ruptured, that's a pretty good indication that it might be bad. However, the only way to know for certain is to check it to see if it has the proper capacitance.
For various reasons it's difficult to test the capacitance of a capacitor which is in a circuit; you'll usually need to detach it and test it in isolation. It is possible to check the equivalent series resistance of a capacitor without removing it from the circuit, and in some cases this may be enough (a correct ESR doesn't necessarily mean the capacitor is good, but an incorrect one means that it's bad).

Does an X-Type Jag have a flux capacitor?
No, the flux capacitor is at this moment in the realms of Science fiction as far as we know.
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.
In replacing the capacitor on a mig welder can i change a 53000 microfarad 30 volts capacitor with a 56000 microfarad 40 volts capacitor?
Yes you can do it. more voltage is good, a little more capacitance is good. Be sure to use a good quality capacitor. Note: on the old capacitor, it might be stated the temperature ratings such as 85 deg. C, 105 deg C, etc. Observe this as well. Higher is better.
What is dc link capacitor?
when the DC current flows through the capacitor .the leakage of the charges is in capacitor called Dc leakage capacitor .
Why does the voltage drop rapidly on your tattoo machine?
Chances are good the capacitor is toast and needs to be changed.
How one can know that what kind of capacitor to use in circuit?
paper capacitor
What capacitor value is good for car battery?
A car battery does not need a capacitor as it's regulating capacity (when in good condition) is well above any capacitor you can fit into your car.
Why is there a C in the equation for a discharging capacitor?
The C represents the capacitance (in farads) of the capacitor. It is a measure of how much charge a capacitor can hold. This is needed to know how much energy the capacitor is holding.
What is coupled capacitor?
There is no coupled capacitor in existence that i know. Capacitors can be used to couple or decouple a signal

How do you take a 2003 Chevy Malibu 3.1 transmission apart?
Leftey loosey, rightey tightey...specifics would be great. Do you know if your flux capacitor is good?
Can a non polarized capacitor be connected to a direct current circuit?
Yes, you can connect a polarized capacitor to a direct current. Make sure you get your polarization is correct.A non polarized capacitor can be connected in a DC circuit as well. "Non Polarized" just means it does not matter which side of the capacitor is positive. If you attempt to connect a polarized capacitor in a DC circuit backwards, you will know when the capacitor explodes.

How do you test a vacuum capacitor?
Jennings has a good tech note on this subject.
Will the capacitor stop car lights from dimming while amp is in use?
when i play music in my car the lights dimm i wanted to know if a capacitor would stop that problem
How can you check your home AC compressor which does not turn on but the fan is running?
Check to see if the capacitor is good. It is usually located inside the outdoor unit. It could be that the capacitor is bad and needs replacing. The outdoor fan will still run if you have a dual capacitor. One sure sign of a blown capacitor is that the top of the capacitor is bowed outward. If you have a multimeter you could also check the amp draw on the condensing unit. I would look at the capacitor first though
