SUMMARY
A negative temperature coefficient of resistance indicates that as temperature increases, the resistance of the material decreases. This phenomenon is primarily observed in semiconductors, where the number of charge carriers increases with temperature, enhancing conductivity. In contrast, metals exhibit a positive temperature coefficient of resistance, where resistance increases with temperature due to increased carrier scattering. Understanding these principles is crucial for applications involving temperature-sensitive electronic components.
