It should be mentioned that here we presented a theoretically perfect (pure) inductor or capacitor that does not have any resistance. Basic Electrical Theory: Electric Current. The electrons in a wire carrying direct current move slowly, but eventually they travel from one end of the wire to the other because they keep plodding along in the same direction. The reactance quantity for an inductor or a capacitor is based on the frequency of the supply current and the DC value of the element itself. Another special example is that the current and voltage are out of phase by 90; this is an essential case because there is no power loss in the circuit when this occurs.
