Variation of resistivity with temperature
{"Image DocumentName": "Variation of resistivity with temperature", "Image ImageDescription": "Why does the resistivity of a metal increase with increasing temperature whereas the resistivity of a semiconductor decrease with increasing temperature? This fact is used in a real semiconductor device called a thermistor, which is used as a temperature sensing element. The thermistor is a temperature \u2013 sensitive resistor; that is its terminal resistance is related to its body temperature. It has a negative temperature coefficient , indicating that its resistance will decrease with an increase in its body temperature.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
