Physics
Semiconductors for JEE Main & Advanced — diodes, transistors, and logic gates
How semiconductor physics appears as a compact but reliable marks source on both papers.
On JEE Main
Main tests p-n junction diode (forward/reverse bias), Zener diode voltage regulation, LED and photodiode operation, transistor in CE configuration, and basic logic gates in single-correct MCQ format.
On JEE Advanced
Advanced uses multi-correct formats for logic gate Boolean algebra (identifying equivalent circuits), transistor load-line reasoning, and combined diode-transistor circuit analysis. This chapter rewards conceptual clarity over formula recall.
How to practise
Practise Semiconductors on PracticeJEE as a compact chapter for quick mark gains before full-length mocks.
