If the frequency of an AC source is given (in hertz) as f, and the value of a capacitor is given (in units called farads) as C, then the capacitive reactance (in ohms), XC, can be calculated using this formula: XC ¼ À1 = ð2fCÞ
-
For instance, a typical D-cell sized electrolytic capacitor will have a storage capacity measured in microfarads, while the same size supercapacitor would store several farads, an improvement of about 10,000 times.
