Скачать или смотреть 04-AC Passing Through an Inductor | Phase Difference & Reactance | Satish Goyal Physics Classes

Welcome to Satish Goyal Physics Classes, your trusted learning platform for Class 11–12 Physics, IIT-JEE, NEET, CBSE, IB, CI and SAT preparation.
In this lecture, we explain one of the most important AC concepts:
AC Passing Through an Inductor (Pure Inductive Circuit)
A pure inductor behaves very differently when AC passes through it, and this lecture makes the entire concept extremely simple and clear.
What You Will Learn in This Video
✔ What happens when AC is applied across a pure inductor
✔ Why current lags voltage by 90° in an inductor
✔ Derivation of the current expression
✔ Understanding inductive reactance (XL = ωL)
✔ Graphical explanation of phase difference
✔ Voltage-current waveforms with correct phasor diagrams
✔ Physical reason behind current lag
✔ Does an inductor consume real power?
✔ Why average power becomes zero in ideal inductor
✔ Instantaneous power explanation
✔ Role of back EMF in inductors
✔ Behavior of inductor in DC vs AC
✔ Conceptual questions for Boards, JEE and NEET
This video helps students understand not just the formulas, but the logic and physics behind inductive circuits, making it extremely useful for competitive exams.
Perfect for:
🔹 CBSE Class 12 Physics Board Exam
🔹 NEET Physics
🔹 JEE Mains & Advanced
🔹 Class 12 AC chapter revision
🔹 Students learning LCR circuits
🔹 Anyone confused about phase difference concepts
