Electric Current and Magnetic Fields: Concepts and Numerical Problem Solving

Many foundational physics courses skip the practical application of formulas, leaving learners unsure how to tackle real-world problems. This course provides a clear, conceptual pathway through the fundamental laws of electricity and magnetism, focusing heavily on step-by-step methods for solving numerical problems and practice exercises. What you'll learn: * Understand the fundamental relationship between charge, potential difference, and current (Ohm's Law). * Apply essential circuit analysis techniques for resistors connected in series and parallel. * Calculate electrical power, energy consumption, and efficiency using standard SI units. * Define and map magnetic fields generated by various current configurations, including straight wires and solenoids. * Practice solving complex numerical problems related to current, resistance, and magnetic forces using structured, repeatable methods. * Analyze the principles of electromagnetic induction and the operation of simple AC and DC devices. The course begins with defining core terminology and units, progresses through circuit laws and calculations, and concludes with the principles of magnetism and induction, reinforced by numerous written examples and practice problems. This course is designed for absolute beginners or students needing a strong foundation in high school level physics; no prior knowledge of advanced calculus or engineering is required.
