NEET 2020 Physics, question 153
Question 153 of the NEET 2020 paper (code E1) is a Physics question from Semiconductor Electronics: Materials, Devices and Simple Circuits. Its idea, p-n Junction: Depletion Region and Biasing, was asked 4 times, in 2017, 2020, 2022 and 2026, across NEET 2017–2026. The NTA final answer key gives option 2.
