Description
Understanding how electrical circuits work is a fundamental skill for anyone entering the world of engineering, electronics, or technology. But for many students, circuit analysis can feel overwhelming—full of abstract concepts, complex equations, and unfamiliar terminology.

This course is designed to change that.

“Mastering DC & AC Circuit Analysis”is a student-friendly, example-rich course that takes you from the very basics of voltage and current to advanced analysis techniques used by engineers every day. Whether you're just starting your academic journey or preparing for exams like the FE/EIT, this course will help you build a rock-solid foundation in circuit theory.

We begin withDC circuits, where you’ll learn the essential laws—Ohm’s Law,Kirchhoff’s Laws, and how to analyze simple and complex resistor networks. You’ll explorevoltage and current dividers,equivalent resistance, andmeasurement techniques, all through clear explanations and real-world examples.

Next, we dive intopowerful analysis methodslikeSuperposition,Thevenin’s and Norton’s Theorems, andNodal and Mesh Analysis. These tools will help you solve even the most complex circuits with confidence.

Then, we transition into the world ofAC circuits, where you’ll learn how to work withphasors,complex impedance, andsinusoidal signals. You’ll apply the same analysis techniques in the AC domain and understand how to calculatepower,power factor, andRMS values—critical concepts in electrical engineering and power systems.

Throughout the course, you’ll benefit from:

Step-by-step walkthroughsof problems

Visual explanationsthat make abstract ideas concrete

Real-world applicationsthat show why these concepts matter

By the end of this course, you won’t just memorize formulas—you’ll understand how and why circuits behave the way they do. You’ll be able to approach any DC or AC circuit with clarity, confidence, and a problem-solving mindset.
