That is the nature of Alternating Current. It is called Alternating current because it changes direction , rather than changing direction because it is alternating current. DC current/voltage is one where the value or amplitude of the signal is always fully positive or negative, for ALL time t, eg I0=0.5A, or I1=â3A.
