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 direction.

What does the abbreviation AC stand for? Meaning: account. How to use ac in a sentence.

2023年6月19日 · An alternating current (AC) is defined as an electric current that changes direction and magnitude periodically. Unlike direct current (DC), which flows in one direction, AC transmits power over long distances with less energy loss.

2024年10月1日 · 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, typically following a waveform like a sine wave.

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 opposite direction, returns again to the original value, and repeats the cycle.

AC is used to refer to an electric current that continually changes direction as it flows. AC is an abbreviation for 'alternating current'.

Alternating current is a current that changes its magnitude and polarity at regular interval of time. It can also be defined as an electrical current which repeatedly changes or reverses its direction opposite to that of Direct Current.

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 construction than DC electromechanical generators.
