Question about Philips Electronics - Others
Ideally you want to check a capacitor with a proper capacitance meter although it can be possible to check them with a multimeter.
If the size of the capacitor is very small, say mircofarads you probably wont be able to test it, however we will give it a try.
Discharge the capacitor first by shorting out the pins. BE WARNED!! IF IT IS A LARGE CAPACITOR OR A CAMERA CAPACITOR DO NOT ATTEMP THIS!! Capacitors can be very dangerous if handled incorrectly.
Find the polarity of the capacitor, there should be a black stripe that runs up the side of the capacitor with a negative sign in it, the leg that is closest to that is the negative.
Set your multimeter to resistance, 10k-1M ohm. Put the probes on the legs of the capacitor and instantly watch the display. The multimeter should show close to 0 ohms and then start increasing slowly. This is because the battery in the multimeter is actually charging the capacitor through the test probes.
If the capacitor shows this pattern then you are pretty much assured that it is working properly.
I must say again though, please be careful around capacitors as they can be very dangerous.
