Displacement Current Between Plates

JEE Main asked Displacement Current Between Plates 7 times in 7 of the 108 shifts Lumi analysed, in 2021, 2022, 2024, 2025 and 2026. It belongs to Parallel Plate Capacitors, in Electromagnetic Waves (Physics). The longest wait between two years asking it was 2 years. In 2021 and 2024 it came in more than one shift of the same year.

Questions on this idea a shift, by year

2017–2026. Asked in 2021, 2022, 2024, 2025 and 2026. Years differ in how many shifts Lumi analysed, so each year is scaled to one shift of 25 Physics questions.
