How to Test a Capacitor With a Multimeter
Most digital multimeters come with an inherent mode to test the value of a capacitor, as shown in Figure 2 (note the symbol of capacitor). This is the most common method for testing a capacitor. A capacitor can be tested for its functionality directly by entering the capacitance mode in the multimeter and performing the following steps:

It consists of at least two electrical conductors separated by a distance. (Note that such electrical conductors are sometimes referred to as "electrodes," but more correctly, they are "capacitor plates.") The space between capacitors may simply be a vacuum, and, in that case, a capacitor is then known as a "vacuum capacitor."
