Alternating Current
|
In alternating current (AC, also ac), the movement of electric charge periodically reverses direction. In direct current (DC, also dc), the flow of electric charge is only in one direction. The abbreviations AC and DC are often used to mean simply alternating and direct, as when they modify current or voltage. AC is the form in which electric power is delivered to businesses and residences. The usual waveform of an AC power circuit is a sine wave. In certain applications, different waveforms are used, such as triangular or square waves. Audio and radio signals carried on electrical wires are also examples of alternating current. In these applications, an important goal is often the recovery of information encoded (or modulated) onto the AC signal. From Wikipedia under the

Asked by richard j - Mon Dec 3 11:47:10 2007 - Physics - 1 Answers - Comments A. Radio waves are electromagnetic waves. They consist of electric field E and magnetic field B. Electric field E induces electric current j = s E. Becuse E(t) is alternating at some frequency f, the current j(t) alternates at the same frequency.
