This chapter provides a comprehensive look at inductors, an essential passive component in electrical circuits. It starts by introducing what an inductor is, explaining the physics behind its energy storage in a magnetic field and why it resists changes in current. Learners explore current symbols, graphical representation of inductance, and methods for calculating current and voltage in inductors, both for simple DC circuits and more complex RLC circuits.
The course explains energy stored in an inductor, and provides techniques for solving problems where current or voltage is given, allowing students to determine the other parameter and the stored energy. Inductors in series and parallel are covered, including equivalent inductance calculations for multi-inductor networks. Comparisons between resistors, capacitors, and inductors highlight their complementary roles in circuits.
Finally, the chapter includes hands-on example problems that demonstrate current and voltage calculations in inductor circuits, preparing students to apply inductors in filters, oscillators, and energy storage systems. By completing this course, learners gain a strong foundation in analyzing and designing inductor-based circuits, an essential skill in both academic and professional electrical engineering.
