Editing Temperature coefficient (section)

===Negative temperature coefficient of resistance===
A '''negative temperature coefficient''' (NTC) refers to materials that experience a decrease in electrical resistance when their temperature is raised. Materials which have useful engineering applications usually show a relatively rapid decrease with temperature, i.e. a lower coefficient. The lower the coefficient, the greater a decrease in electrical resistance for a given temperature increase. NTC materials are used to create inrush current limiters (because they present higher initial resistance until the current limiter reaches quiescent temperature), [[temperature sensor]]s and [[thermistor]]s.
