Complete the following statement with the most appropriate answer from the options.
The resistivity of conductors ____ and that of semiconductors ____ with increase in temperature.
Answer & explanation
Correct answer: option 4
- For metals, with increase in temperature, the kernels start vibrating more rigorously, thereby, offering more resistance to the flow of electrons.
- For semiconductors, with increase in temperature, the covalent bonds start breaking, thereby, releasing more carriers for conduction.
