| Solar cell | The band gap a material should have for use in a solar cell |
| Transistor amplifier | The AC current gain, load resistance and input resistance of a common emitter amplifier, and the base current of an NPN transistor when 80% of the electrons reach the collector |
| Logic gates | The Boolean expression for a combination of gates, and the inputs for which the output Y is 1 |
| Semiconductor materials | The energy levels occupied by the electrons donated by impurity atoms in an n-type semiconductor, and the conductivity of insulators |
How to Use the Semiconductor Devices PYQ PDF for MHT CET
- Start with the 2025 and 2026 papers first, because they hold 98 of the 235 questions.
- Start with the largest group, the diode and rectifier questions, and then do the logic gate truth tables.
- Keep α = Ic/Ie, β = Ic/Ib and β = α/(1 - α) together for the transistor questions.
- 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.
