All engineering aspirants want to take admission in prestigious engineering colleges by clearing national level engineering entrance test i.e., Joint Entrance Examination (JEE). But it is not possible as number of seats in these colleges is very less as compared to number of aspirants.
Uttar Pradesh State Entrance Examination (UPSEE) is a state level engineering entrance examination for degree level engineering institutions and other professional colleges. It is easier to crack UPSEE than JEE.
In this article, UPSEE aspirants will get chapter notes of chapter Electronic Devices based on the latest syllabus of UPSEE examination. About 1-2 questions are always asked from this topic in the examination.
About the notes:
These notes are prepared by Subject Experts of Physics after observing the pattern of some previous year papers of UPSEE examination.
In these notes, all important topics related to Electronic Devices like classification of solids, intrinsic semiconductor, extrinsic semiconductor, p-n junction, photodiode, Light Emitting Diode(LED), solar cell etc are included.
