Alternating current (AC) is an electric current that periodically reverses direction and changes its magnitude continuously with time, in contrast to direct current (DC), which flows only in one …

Jan 9, 2026 · Alternating current (AC), flow of electric charge that periodically reverses. It starts from zero, grows to a maximum, decreases to zero, reverses, reaches a maximum in the …

Jun 19, 2023 · An alternating current is an electric current that changes its direction and magnitude periodically. It has many advantages over direct current for power transmission and …

Jun 10, 2025 · Alternating current (AC) is a type of electric current that periodically reverses its direction of flow. Its polarity changes over time, and its magnitude fluctuates sinusoidally, …

Dec 28, 2025 · The meaning of ALTERNATING CURRENT is an electric current that reverses its direction at regularly recurring intervals —abbreviation AC.

Alternating current Alternating current (AC) is the type of electric current generated by the vast majority of power plants and used by most power distribution systems.

Sep 1, 2025 · Definition of Alternating Current (AC) We know in DC circuits, the current is made to flow in a uniform direction. However, electric charge can also flow periodically in reverse …

An electric current that frequently reverses direction is called an alternating current (AC). Once again, whether the intensity of the current remains constant is irrelevant. The frequent reversal …

An electric current that repeatedly changes its direction or strength, usually at a certain frequency or range of frequencies. The term is also used to describe alternating voltages.

AC stands for “Alternating Current,” meaning voltage or current that changes polarity or direction, respectively, over time. AC electromechanical generators, known as alternators, are of simpler …
