DC Circuit Analysis

Master the foundational principles of electrical engineering in this comprehensive course on DC Circuit Analysis. Led by Fawad Albandi, a Professional Engineer in electrical power engineering and an instructor at Johns Hopkins University, this course bridges the gap between theoretical concepts and practical industry application. Designed for engineering students and professionals alike, the content provides a rigorous examination of direct current electrical networks, equipping learners with the mathematical tools and theorems necessary to analyze complex circuits effectively.

The course begins by establishing the core definitions of electrical potential, current, resistance, and conductance, alongside the application of Ohm's Law. As the curriculum progresses, learners will explore methods for simplifying circuits through series and parallel resistor combinations, as well as Delta-to-Wye and Wye-to-Delta conversions. A significant portion of the course is dedicated to the fundamental laws that govern network analysis, specifically Kirchhoff's Voltage Law (KVL) and Kirchhoff's Current Law (KCL). Students will also gain proficiency in using powerful network theorems such as Thevenin and Norton equivalents, the Superposition Principle, and Source Transformation to reduce complex networks into manageable forms.

Key topics covered in this course include:

• Fundamental units and definitions: Voltage, Current, Resistance, and Conductance.
• Application of Ohm's Law and finding Equivalent Resistance in series and parallel circuits.
• Voltage and Current Divider rules for circuit analysis.
• Comprehensive coverage of Kirchhoff’s Voltage Law (KVL) and Kirchhoff’s Current Law (KCL).
• Network simplification using Delta-to-Y and Y-to-Delta conversions.
• Essential Network Theorems: Thevenin’s Theorem, Norton’s Theorem, and the Superposition Principle.
• Source Transformation techniques and analyzing power consumption.
• Conditions for Maximum Power Transfer to a load.
• Systematic problem-solving using the Loop Method and Node Method of circuit analysis.

By the end of this course, participants will have a solid understanding of how to calculate voltage drops, branch currents, and power dissipation across various components. Whether utilizing matrix algebra for Loop and Node analysis or applying fundamental conservation laws, learners will develop a robust skillset for solving linear DC circuits with precision.
