Question Style in MHT CET Transistors PYQs

Every question in this PDF is a single-correct MCQ. Most of them (33 of 41) are short numerical questions on the common emitter amplifier.

Question Style	What it Tests
Current and voltage gain	A common emitter amplifier with an AC current gain of 65, a given load resistance and input resistance, and the voltage gain
Base and collector currents	An n-p-n transistor with a collector current of 28 mA when 80% of the electrons reach the collector, and the base current
Power gain	The ratio of power gain to voltage gain in common emitter configuration
α and β relations	The current gain when I_C / I_E = 0.95, and β from α = 0.98
Doping	Which of the emitter, base and collector is heavily doped and which is lightly doped

How to Use the Transistors PYQ PDF for MHT CET

Start with the 2025 and 2026 papers first, because they hold 22 of the 41 questions.
Keep α = Ic/Ie, β = Ic/Ib, Ie = Ib + Ic and the gain formulas for the common emitter amplifier on one page.
For the electron-count questions, convert the percentage of electrons reaching the collector into Ic/Ie first.
Solve year-wise PYQs by timing yourself, as time management is crucial.
Re-attempt only the questions you got wrong, and note which formula or step you missed.
