QJEEM23Ph701e: JEE Main 2023 Physics - Class 12 JEEM23Ph701e Solution: The effect of increase in temperature on the number of…

The effect of increase in temperature on the number of electrons in conduction band ( ne\mathrm{n_e} ) and resistance of a semiconductor will be as:

Multiple Choice Options

  • A ne\mathrm{n}_{\mathrm{e}} decreases, resistance increases
  • B Both ne\mathrm{n}_{\mathrm{e}} and resistance increase
  • C ne\mathrm{n}_{\mathrm{e}} increases, resistance decreases
  • D Both ne\mathrm{n}_{\mathrm{e}} and resistance decrease

Step-by-Step Verified Solution

As temperature increases nen_{e} increases, this results in increase in conductance.

∴T\therefore T increases, nen_{e} increases and RR decreases.
