AC Circuit Analysis

AC circuit analysis involves studying how alternating current (AC) flows through electrical components over time. Unlike direct current (DC), which flows in one direction, AC changes direction periodically. Engineers analyze these circuits by measuring quantities like voltage, current, resistance, and their phase differences using tools like oscilloscopes and complex math involving impedance. This helps to understand how devices perform under AC power, optimize performance, and ensure safety. AC analysis is essential in designing and troubleshooting electrical systems such as power grids, appliances, and communication devices, ensuring they operate efficiently and reliably.
