Engineering Circuit Analysis, also known as Circuit Theory, is difficult for most students primarily because the basic laws seem very simple. This leads the student to believe that the exam problems will not be too difficult, when in reality there is a large amount of technique in solving circuit problems.We begin this course assuming that the student knows absolutely nothing about the solution methods to be learned. We introduce the concept of the time contant early in this course and take time to explain what the physical meaning of the time constant really is. Next, we explore the natural response of circuits that have Inductors and Resistors (LR) and Capacitors with Resistors (RC).Next, explore and solve problems that deal with the step response of circuits in which a source is connected to the capacitor or indivtive load by a switch. These types of circuits are very common in circuit analysis and all students must master this material.With these tools, the student will be able to solve a wide variety of engineering level circuit problems with confidence.Disk 1Sect 1: Introduction to Natural and Step ResponseSect 2: Natural Response of LR CircuitsSect 3: Time Constant of LR CircuitsSect 4: LR Natural Response Circuit Problems, Part 1Sect 5: LR Natural Response Circuit Problems, Part 2Sect 6: LR Natural Response Circuit Problems, Part 3Disk 2Sect 7: Natural Response of RC CircuitsSect 8: RC Natural Response Circuit Problems, Part 1Sect 9: RC Natural Response Circuit Problems, Part 2Sect 10: Step Response of LR CircuitsSect 11: LR Step Response Circuit ProblemSect 12: Step Response of RC CircuitsSect 13: RC Step Response Circuit ProblemSect 14: General Solution of Step and Natural ResponseSect 15: Use General Form to Solve Problems
