AC Fundamentals & Resonance

AC Fundamentals & Resonance

Alternating Current (AC) is an electric current which periodically reverses direction, in contrast to Direct Current (DC) which flows only in one direction. AC is the form in which electric power is delivered to businesses and residences, and it is the form of electrical energy that radio waves carry. Its ability to be easily transformed to different voltage levels makes it highly efficient for power transmission over long distances.
