Energy Stored in Inductors

JEE Main asked Energy Stored in Inductors 7 times in 7 of the 108 shifts Lumi analysed, in 2020, 2021, 2022, 2023 and 2026. It belongs to Inductance, in Electromagnetic Induction (Physics). The longest wait between two years asking it was 3 years. In 2021 it came in more than one shift of the same year.

Questions on this idea a shift, by year

2017–2026. Asked in 2020, 2021, 2022, 2023 and 2026. Years differ in how many shifts Lumi analysed, so each year is scaled to one shift of 25 Physics questions.
