How do you test a capacitor?
There are several ways to test a capacitor to see if it still functions as it should. Disconnect the capacitor from the circuit it is part of. Read the capacitance value on the outside of the capacitor. The unit for capacitance is the farad, which is abbreviated with a capital “F.”
How do you measure the capacitance of a capacitor?
You may also see the Greek letter mu (µ), which looks like a lowercase “u” with a tail in front of it. (Because the farad is a large unit, most capacitors measure capacitance in microfarads; a microfarad is a millionth of a farad.) Set your multimeter to its capacitance setting.
