AC Circuit Theory Fundamentals

Mastering alternating current is essential for anyone studying electrical engineering, electronics, or physics. This course provides a clear, step-by-step introduction to the core principles governing AC circuits, breaking down complex mathematics into approachable concepts. You will transition from basic electrical definitions to confident analysis of single-phase alternating current networks using analytical methods. What you'll learn: - Understand fundamental AC wave characteristics, including frequency, period, amplitude, and RMS values - Apply complex numbers and phasor notation to represent sinusoidal voltages and currents - Calculate impedance and admittance for resistors, inductors, and capacitors across various frequencies - Solve alternating current networks using Kirchhoff's laws, nodal analysis, and mesh techniques in the frequency domain - Analyze real, reactive, and apparent power alongside power factor correction concepts - Evaluate frequency response and resonance behavior in series and parallel RLC circuits The course begins with foundational terminology and mathematical prerequisites before advancing through component behaviors, phasor transformations, and full circuit calculations through practical text-based walkthroughs and exercises. This course is designed for engineering students, technicians, and hobbyists with basic knowledge of direct current circuits who want to build a solid foundation in AC analysis.
