Question

what is a Alternating Current

Answer 1

Alternating current (AC) is an electric current that reverses direction periodically. It is the most common form of electricity used in homes and businesses, as it is able to travel long distances more efficiently than direct current (DC). In an AC circuit, the flow of electric charge changes direction rapidly, typically 50 to 60 times per second in most parts of the world, creating a sinusoidal waveform. This constant change in direction allows AC to power devices that require varying voltage and current levels.
