Question

Which of the following describes the temperature dependence of semiconductors?

विकल्प

• Their resistivity increases when the temperature increases

• Their resistivity decreases when the temperature increases

• Their resistivity is independent of temperature changes

• Their resistivity becomes infinite at high temperatures

Answer 1

Semiconductors exhibit the opposite temperature behavior compared to metals. In semiconductors, resistivity decreases when the temperature increases. This unique property makes semiconductors useful in electronic components and is a key difference tested in exams.
