As the temperature increases, the electrical resistance (a) Increases for both conductors and semiconductors (b) Decreases for both conductors and semiconductors (c) Increases for conductors but decreases for semiconductors (d) Decreases for conductors but increases for semiconductors

Answer: (c). Conductors: more lattice vibration at higher T increases collisions, so R increases. Semiconductors: more carriers are generated at higher T, so R decreases. So the answer is (c).

Intrinsic & Extrinsic Semiconductors

As the temperature increases, the electrical resistance

Show answer and solution

Answer: (c)

Conductors: more lattice vibration at higher $T$ increases collisions, so $R$ increases.
Semiconductors: more carriers are generated at higher $T$ , so $R$ decreases.
So the answer is (c).
