alternating electric current

[GrompelFem]

an electric current that reverses direction sinusoidally

[Welington Mina]

Alternating electric current, also known as AC, is a type of electrical current where the direction of flow of electric charge periodically reverses. This means that the voltage level also alternates between positive and negative values. Unlike direct current (DC), where electricity flows in one direction, AC can easily be transformed to different voltage levels, making it ideal for generating and supplying electricity over long distances.
