Forward and Reverse Biasing

JEE Main asked Forward and Reverse Biasing 6 times in 6 of the 108 shifts Lumi analysed, in 2022, 2023, 2024 and 2026. It belongs to Semiconductor Diodes, in Semiconductor Electronics: Materials, Devices and Simple Circuits (Physics). The longest wait between two years asking it was 2 years. In 2023 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 2022, 2023, 2024 and 2026. Years differ in how many shifts Lumi analysed, so each year is scaled to one shift of 25 Physics questions.
