Essential Circuit Analysis: DC and AC Fundamentals

Electrical circuits are the backbone of modern technology, but understanding their behavior requires mastering foundational analysis techniques. Start your journey into electrical engineering by building a solid theoretical base. By the end of this course, you will be proficient in applying core laws and theorems to determine voltage, current, and power across linear components. You will gain the skills necessary to analyze circuits in both steady-state DC and single-frequency AC conditions. What you'll learn: * Understand the fundamental concepts of charge, current, voltage, resistance, and basic component models (resistors, inductors, capacitors). * Apply Kirchhoff’s Current Law (KCL) and Voltage Law (KVL) to solve complex resistive networks using nodal and mesh analysis. * Master circuit simplification techniques including source transformations, superposition, Thevenin’s, and Norton’s theorems. * Analyze sinusoidal steady-state circuits using phasors and complex impedance for AC component behavior (R, L, C). * Practice calculating power relationships in AC circuits, including real power, reactive power, and power factor correction concepts. * Learn the principles of basic circuit modeling and verification techniques used in modern electrical simulation workflows. The course begins with defining key electrical concepts and mastering fundamental DC analysis methods. It then transitions into the time domain, introducing reactive components and culminating in comprehensive single-frequency AC circuit analysis. This course is designed exclusively for beginners with no prior experience in electrical engineering or circuit theory. No prerequisites are required to start learning.
