The pair production and intrinsic conductivity both are low at _.
Correct answer: C. Room temperature
- A. Road temperature
- B. Hall temperature
- C. Room temperature
- D. None of these
Explanation
At room temperature (usually around 20-25°C or 68-77°F), both pair production and intrinsic conductivity in semiconductors are relatively low compared to higher temperatures. While electrons can still gain enough energy to move and generate electron-hole pairs at room temperature, the thermal energy available is less compared to higher temperatures, resulting in a lower rate of pair production and intrinsic conductivity in semiconductors.

About Electrical Properties of Solids
Electrical properties of solids depend on their band structure, charge carriers and conductivity. The topic compares conductors, insulators and semiconductors, relates resistivity to temperature, and covers intrinsic and extrinsic semiconductors, donor and acceptor impurities, electron and hole conduction, and the formation of p-type and n-type materials.
