WebCan DC current produce electromagnetic waves? Question: How are DC signals perceived as EM waves? Answer: They aren’t EM waves, because by definition a DC signal (or power) is unchanging, so there can be no wave propagation going on. It is important to understand that fluctuating DC cannot exist – anything that fluctuates is actually AC.
