Quizplus · Accepted Answer

Alternating current is a type of current where the direction of electron flow constantly changes, typically 60 times per second (in the US). It is the most commonly used type of current in households and industry, as opposed to direct current which flows in only one direction. Solid-state modules and electronic air filters could certainly use alternating current.
