Is LC oscillation in syllabus class 12 board?

No, LC oscillations (L = Inductance, C = Capacitance) have generally been removed from the CBSE Class 12 Physics syllabus for recent academic years (including 2024-25 and 2025-26) as part of syllabus rationalization, though it might still appear in some state boards or competitive exam prep. It's crucial to check your specific board's official syllabus, but for CBSE, it's a deleted topic from the Alternating Currents chapter.

What is LC Oscillation class 12th?

LC oscillation refers to the continuous flow of electrical energy between a capacitor and an inductor in an ideal LC circuit. Key points: Energy shifts between the electric field (capacitor) and magnetic field (inductor). It produces undamped, sinusoidal oscillations at a natural frequency.
