Faraday's First Law
JEE Main asked Faraday's First Law 2 times in 2 of the 108 shifts Lumi analysed, in 2022 and 2024. It belongs to Faraday's Laws of Electrolysis, in Electrochemistry (Chemistry). The longest wait between two years asking it was 2 years.

Questions on this idea a shift, by year
2017–2026. Asked in 2022 and 2024. Years differ in how many shifts Lumi analysed, so each year is scaled to one shift of 25 Chemistry questions.
Raw count: 2017: 0 in 1 shift · 2020: 0 in 12 shifts · 2021: 0 in 24 shifts · 2022: 1 in 24 shifts · 2023: 0 in 12 shifts · 2024: 1 in 18 shifts · 2025: 0 in 8 shifts · 2026: 0 in 9 shifts.
