So, What is all this Fuss about LED Lights
... What is an LED, anyway? An LED (which is usually pronounced as the letters L.E.D. but also is used as an acronym pronounced like the metal, "lead") is a Light Emitting Diode - a semiconductor device that emits light when a voltage is applied (typically 2.1 volts dc). LEDs work differently than Ediso ...

Alternating current
Alternating current (AC), is an electric current in which the flow of electric charge periodically reverses direction, whereas 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 alternating current in most electric power circuits 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. These types of alternating current carry information encoded (or modulated) onto the AC signal, such as sound (audio) or images (video).
