CE Amplifier Voltage Gain

JEE Main asked CE Amplifier Voltage Gain 7 times in 7 of the 108 shifts Lumi analysed, in 2021, 2022 and 2023. It belongs to Transistors, in Semiconductor Electronics: Materials, Devices and Simple Circuits (Physics). The longest wait between two years asking it was 1 year. In 2022 and 2023 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 and 2023. Years differ in how many shifts Lumi analysed, so each year is scaled to one shift of 25 Physics questions.
