Why is resistivity inversely proportional to resistance for NTC semiconductors?

In summary, resistivity and resistance are both important parameters in NTC semiconductors that are affected by changes in temperature. The resistivity of NTC semiconductors is inversely proportional to their resistance, meaning that as temperature increases, both values decrease. Other factors such as impurities and material composition can also affect the resistance of NTC semiconductors. However, this relationship between resistivity and resistance is specific to NTC semiconductors and does not apply to PTC semiconductors, which have a positive relationship between resistivity and resistance.
