Electronic Circuits: Understanding DC and AC Fundamentals

Understanding how electricity behaves in circuits is the essential first step toward mastering electronics, electrical engineering, or physics. This course provides a solid, text-based foundation in circuit theory, teaching you how to apply fundamental laws and mathematical techniques to solve both direct current (DC) and alternating current (AC) problems. What you'll learn: * Understand the core concepts of charge, current, voltage, power, and energy within a circuit context. * Apply Kirchhoff's Voltage Law (KVL) and Kirchhoff's Current Law (KCL) for systematic circuit analysis. * Master techniques like nodal analysis and mesh analysis to solve complex DC circuits efficiently. * Analyze the behavior of inductors, capacitors, and resistors in both DC steady-state and time-domain AC circuits. * Practice using source transformations, superposition, and Thevenin/Norton equivalents for circuit simplification. * Configure simple passive filter circuits, understanding their frequency response and practical applications. The course begins with clear definitions and basic quantities, progressing systematically through essential DC analysis methods before introducing reactive components and the fundamentals of AC circuit behavior. This course is designed for absolute beginners—no prior knowledge of electronics, circuit theory, or advanced mathematics is required beyond basic algebra.
