$...............$Electric circuits are fundamental to understanding electrical engineering. The study covers principles of voltage, current, resistance, and power in DC and AC circuits, analyzing their behavior using Ohm's law and Kirchhoff's laws. Components such as resistors, capacitors, inductors, and operational amplifiers are integral to circuit analysis and design, including their applications in filters, amplifiers, and signal processing. Theoretical bases extend to electromagnetism, including Maxwell's equations for understanding electromagnetic fields, transmission lines, wave propagation, and antennas. Power systems theory explores generation, transmission, and distribution, addressing stability, fault analysis, and protection schemes. Control theory applies to feedback systems, automation, and robotics, essential in modern electrical applications.
