Foundational Principles of Electric Circuits: DC and AC Analysis

Electricity is the backbone of modern technology, but understanding how circuits function requires mastering fundamental physics and mathematical principles. This course provides the foundational knowledge needed to confidently approach circuit analysis. By the end of this course, you will be able to read circuit diagrams, apply Ohm's and Kirchhoff's laws to solve for unknown quantities, and understand the behavior of basic components like resistors, capacitors, and inductors in both DC and AC environments. What you'll learn: * Understand the concepts of voltage, current, resistance, and power, and apply Ohm's Law effectively. * Apply Kirchhoff's Current Law (KCL) and Voltage Law (KVL) to analyze complex series and parallel DC circuits. * Master advanced DC analysis techniques, including nodal analysis, mesh analysis, superposition, and Thevenin/Norton equivalents. * Learn the behavior of capacitors and inductors, and analyze transient responses in first-order RL and RC circuits. * Practice AC circuit analysis using phasors, impedance, and resonance concepts for steady-state sinusoidal response. * Configure and analyze basic passive filter circuits (low-pass and high-pass) using fundamental component arrangements. The course begins with definitions and fundamental laws, progresses through DC circuit techniques, and concludes with a deep dive into component behavior and alternating current (AC) analysis. You will work through detailed, written examples and practical exercises to reinforce every concept. This course is designed for absolute beginners interested in electrical engineering, electronics, or physics. No prior knowledge of circuit theory is required, only basic algebra skills.
