A capacitor consists of two conductors separated by an insulator, also known as a dielectric. Capacitive reactance is an opposition to the change of voltage across an element. Capacitive reactance is inversely proportional to the signal frequency (or angular frequency ) and the capacitance . There are two choices in the literature for defining reactance for a capacitor. One is to use a unif…
