Is LC oscillation in syllabus class 12?

Yes, LC oscillations are generally part of the CBSE Class 12 Physics syllabus, specifically within the Alternating Current chapter, though sometimes covered with a qualitative treatment focusing on the energy exchange between inductor (L) and capacitor (C) and the concept of resonance. While some specific details or advanced derivations might be removed in certain years, the fundamental concept of LC oscillations and their role in tuning circuits (like radios) remains important for conceptual understanding and competitive exams like JEE.

What is LC oscillation Class 12?

LC oscillations are generated due to the continuous energy flow from the capacitor to the inductor. In this, the capacitor undergoes charging, discharging, charging, etc. The capacitor starts charging the inductor while discharging itself when a charged capacitor is connected to a de-energized inductor.
