AC (Alternating Current) circuit theory is a branch of electrical engineering that deals with circuits carrying alternating current, which periodically changes direction. It is crucial for understanding the behavior of electrical systems, including power generation, transmission, and distribution. AC circuit theory involves analyzing voltage, current, impedance, and power relationships in circuits with components like resistors, capacitors, and inductors. The study of AC circuits is essential for designing and troubleshooting electrical systems used in a wide range of applications, from household appliances to industrial machinery. Key concepts include phasors, impedance, complex numbers, and the use of tools like phasor diagrams and AC circuit analysis techniques to solve problems in AC circuits.
