Statement-I: The temperature coefficient of resistance is positive for metals and negative for semiconductors.

Statement-II: On raising the temperature, in metals drift velocity increases but in semiconductors more charge carriers are released.

View answer and explanation

Correct option: A

If both statements are correct.

Option A (If both statements are correct) is correct because metals have a positive temperature coefficient of resistance, while semiconductors have a negative one due to increased carrier concentration with temperature.
