Alternating Current (AC)
Electrical current flow that reverses direction on a periodic basis. This is the way our normal household electricity works. Alternating the current flow makes it easier for electrical power to be efficiently distributed over vast distances. In the United States our current changes direction at a rate of 60 times per second (60 Hz). Audio signals are also alternating, with the frequencies corresponding to the frequencies of the sounds present.

Our Customers Say...

“My Sales Engineer is the best. If I need it tomorrow, I have it tomorrow. He makes sure everything is in order and that I'm set up right. I've spent a lot of money at other places, too, but I don't remember them calling me to make sure everything's okay.”
