Impedance at Resonance

JEE Main asked Impedance at Resonance 5 times in 5 of the 108 shifts Lumi analysed, in 2021, 2022 and 2024. It belongs to LCR Resonance, in Alternating Current (Physics). The longest wait between two years asking it was 2 years. In 2021 and 2022 it came in more than one shift of the same year.
