Physics of Electricity: Current, Circuits, and Resistance

Electric phenomena are essential to modern life, but the underlying physics can seem complex. This course breaks down the core concepts of electricity into clear, accessible explanations. By the end of this program, you will have a solid theoretical understanding of how electric current flows, how resistance affects circuits, and how fundamental laws like Ohm's Law and Kirchhoff's Laws govern electrical behavior. This knowledge provides the bedrock for further study in electronics and electrical engineering. What you'll learn: * Understand the definitions of electric charge, potential difference (voltage), and electric current. * Apply Ohm's Law to calculate relationships between voltage, current, and resistance in basic circuits. * Analyze the properties of resistors connected in series and parallel configurations. * Learn the foundational principles of electrical power and energy dissipation. * Practice using Kirchhoff's Current and Voltage Laws for solving complex DC circuit problems. The course begins by defining key terminology and physical concepts, then progresses through practical applications of fundamental laws, culminating in techniques for analyzing complex circuit arrangements through written examples. This course is designed for absolute beginners in physics and electrical concepts. No prior knowledge of calculus or advanced mathematics is required, only basic algebra skills.
