Lesson 13 - Circuit Analysis Using Kirchhoff's Laws, Part 7 (Engineering Circuit Analysis)
About this course
Understanding what really happens inside an electrical circuit is a practical skill that supports faster troubleshooting, safer work, and better design decisions. This free online course in Engineering Circuits Analysis is designed to help you move from memorizing formulas to confidently interpreting real circuit behavior. Whether you are stepping into electrician-related roles or strengthening professional skills for technical work, you will learn to connect core theory with the calculations you need on the job.
You begin by clarifying the fundamentals of voltage, current, and resistance, then build toward a working understanding of common circuit components and why they matter in analysis. Along the way, you practice applying Ohm’s Law with clear, realistic scenarios that show how to compute unknown values and verify whether results make sense. Power calculations are treated as more than just math, helping you recognize what power means for components, losses, and safe operation.
A major focus is developing confidence with Kirchhoff’s Current Law and Kirchhoff’s Voltage Law. Instead of treating them as abstract rules, you learn how to use them as a reliable method for breaking down both simple and more complex networks with nodes and loops, including cases with current sources. You will also encounter dependent sources and learn how their values relate to other circuit variables, which is essential for analyzing many practical and educational circuit models.
As you progress, you strengthen your ability to simplify networks using series and parallel resistance, then apply that foundation to voltage divider and current divider reasoning. The built-in exercises reinforce each concept so you can build accuracy, speed, and intuition, making circuit calculations feel consistent and repeatable. By the end, you will be better prepared to analyze circuits logically, justify each step, and approach electrical problems with the structured mindset used in engineering practice.
