Introduction to Electric Circuit Networks and Network Theorems

Every advanced system in electrical engineering, from smart power grids to microchips, relies on the fundamental principles of circuit networks. Understanding how current and voltage behave across components is the essential first step for any aspiring engineer or hobbyist. This course guides you from absolute beginner concepts to confidently analyzing complex electrical systems using proven mathematical theorems. You will start by learning core terminology, electrical variables, and the fundamental behavior of resistors, capacitors, and inductors in a network. Next, you will explore how these elements interact under key network theorems, building a solid mental model of circuit behavior. What you will learn: Understand foundational concepts of voltage, current, resistance, capacitance, and inductance; Apply Ohm's Law and Kirchhoff's Laws to analyze basic series and parallel circuits; Master core network theorems including Thevenin's, Norton's, and Superposition theorems; Analyze alternating current (AC) basics alongside traditional direct current (DC) network behaviors; Practice solving circuit equations step-by-step using structured nodal and mesh analysis methods. This written course is structured to build your confidence step-by-step, starting with basic definitions before moving into systematic network analysis and theorem applications. This course is designed specifically for beginners, students, and hobbyists with no prior background in electrical engineering.
