  1. Question 1

    Q1. What is the effect of increasing the temperature on the resistivity of a semiconductor?

    • A) Resistivity increases
    • B) Resistivity decreases
    • C) Resistivity remains the same
    • D) Resistivity becomes zero

    Answer: Resistivity decreases

    Explanation: In semiconductors, increasing temperature provides more charge carriers, decreasing resistivity. Option A is incorrect as it's opposite to what's observed in semiconductors.
