Question

How does the resistivity of semiconductors compare to that of conductors and insulators?

Options

• Semiconductors have resistivity higher than conductors but much lower than insulators

• Semiconductors have the lowest resistivity of all three classes

• Semiconductors have the highest resistivity of all three classes

• Semiconductors have resistivity equal to conductors

Answer 1

Semiconductors occupy an intermediate position in the resistivity spectrum. They have resistivity higher than conductors like copper, allowing them to restrict current flow more than conductors do, but their resistivity is much lower than insulators, meaning they still conduct significantly more current than insulators.
