Core Concepts of Electricity, Magnetism, and Optics

Physics provides the language for understanding how the technical world operates, but concepts like electromagnetism and wave behavior can be challenging to grasp. This text-based course breaks down complex physical principles into clear, digestible explanations and practical applications. By the end of this course, you will have a robust understanding of the core concepts of advanced classical and modern physics. You will be equipped to apply fundamental physical laws to analyze circuits, predict wave behavior, and solve quantitative problems in fields like electrical engineering and photonics. What you'll learn: * Understand the principles of electrostatics, including Coulomb's Law, electric fields, and electric potential energy. * Analyze direct current (DC) circuits using Kirchhoff's laws and calculate resistance and power dissipation. * Master the relationship between moving charges and magnetic fields using the Biot-Savart Law and electromagnetic induction. * Apply the laws of reflection, refraction, and diffraction to understand the behavior of light and optical instruments. * Learn the foundational concepts of modern physics, including the photoelectric effect, atomic structure, and basic semiconductor function. The course begins with foundational definitions in electrostatics before moving methodically through current electricity, magnetism, electromagnetic induction, and the principles of optics. The final sections introduce the basic concepts of modern physics and quantum phenomena. This course is designed for absolute beginners and students seeking a comprehensive review of foundational physics concepts required for university-level science or engineering programs.
