PTC (positive temperature coefficient) material is a kind of thermo-sensitive material. In this study, a series of … resistance–temperature coefficient increases. A critical heating power defined as the initial heating power which makes the … coefficient of PTC materials, and a higher Curie temperature or resistance–temperature coefficient will lead to a larger critical …
