Alternating Current

Alternating Current (AC) is a fundamental concept in electrical engineering and physics, referring to the flow of electric charge that periodically reverses direction. Unlike direct current (DC), which flows in a single direction, AC is characterized by its sine wave form, making it the preferred choice for power distribution systems worldwide. This category encompasses a range of topics, including the principles of AC generation, circuit analysis, transformers, and applications in household and industrial settings. Understanding AC is crucial for mastering electrical systems and technologies that power our modern world.
