Foundations of Network Theory and Circuit Analysis

Understand how electrical circuits function by mastering the fundamental laws that govern them. This course provides a clear, step-by-step introduction to network theory, helping you build a solid foundation in circuit behavior without complex jargon. You will transition from recognizing basic electrical components to confidently analyzing DC circuits. By learning how to systematically apply core network theorems, you will gain the skills needed to calculate currents, voltages, and power distribution in various network configurations. What you'll learn: - Understand foundational terminology, including nodes, branches, loops, and meshes. - Classify active and passive circuit elements, such as resistors, capacitors, inductors, and energy sources. - Apply Kirchhoff's Current Law (KCL) and Kirchhoff's Voltage Law (KVL) to simple networks. - Formulate circuit equations using nodal and mesh analysis techniques. - Analyze networks using key theorems including Thevenin's, Norton's, and Superposition theorems. - Practice solving practical circuit problems through structured, text-based walkthroughs. This course begins with essential definitions and the physics of charge and energy before moving into practical circuit laws and systematic analysis methods. It concludes with an overview of modern modeling concepts used in circuit simulation tools today. This course is designed for absolute beginners, engineering students, and hobbyists looking for a clear, written guide to circuit theory. No prior background in electrical engineering is required.
