LC Oscillations — Previous-Year Questions
5 previous-year questions on LC Oscillations, drawn from JEE Mains, JEE Advanced, NEET UG, and CUET papers. Every question carries a worked-out explanation.
Q1. L = 0.02 H, C = 50 μF. Period of LC oscillation:
JEE 2022Q2. In an LC oscillation, at t = T/4 the energy is:
JEE 2021Q3. Capacitor initially has 5 mC at 100 μF. Peak current in an LC oscillation with L = 25 mH:
JEE 2020Q4. Mechanical analogue of an LC oscillator is:
JEE 2019Q5. If both L and C are doubled, the period of LC oscillation becomes:
JEE 2018LC Oscillations previous-year questions from sciphylab (also known as SciPhy, SciPhy Lab, SciPhy Labs, Physics Lab). Class 12 physics practice for JEE Mains, JEE Advanced, NEET UG, AP Physics 1/2/C, SAT, and CUET-UG candidates.
