Foundations of DC and AC Circuits

Understanding electrical circuits is the foundation of modern technology, yet grasping the core behavior of currents can feel overwhelming without a structured approach. This text-only course demystifies electrical engineering concepts by breaking down complex theories into clear, digestible written explanations. You will transition from learning basic electrical terms to confidently analyzing both direct current (DC) and alternating current (AC) networks. What you'll learn: - Understand fundamental electrical quantities including voltage, current, resistance, and power. - Analyze DC circuits using essential methods like Ohm's Law, Kirchhoff's Laws, and nodal analysis. - Master AC circuit principles, including frequency, phase shifts, impedance, and waveforms. - Calculate power factors and understand the role of capacitors and inductors in AC systems. - Practice solving circuit analysis problems step-by-step using clear, written equations. This course begins with essential terminology and foundational physics concepts before guiding you through practical DC and AC analysis techniques. Each section builds upon the last, ensuring you develop a strong intuitive grasp of electrical behavior through comprehensive written examples and exercises. This course is designed specifically for beginners, engineering students, and hobbyists with no prior background in circuit theory.
