# AC Circuits

AC circuits, or alternating current circuits, play a pivotal role in the realm of electrical engineering. Unlike their DC counterparts, AC circuits carry a dynamic flow of electricity that oscillates in both magnitude and direction. This constant variation facilitates efficient energy transfer over long distances and is a fundamental component in powering countless devices and systems. Understanding the principles governing AC circuits is essential for engineers and technicians, as they form the backbone of electrical distribution networks, household appliances, and industrial machinery. Delving into the intricacies of AC circuits unveils the foundation upon which modern electrical systems thrive.
