Models Used in V-I Measuring Curve of PTCR
Yongde Hao, Aac Electrorrice · 2004
Analyses the static volt-ampere characteristic curve of positive temperature coefficient thermal resistor (PTCR) in detail.Recommend a mathematics method to deal with testing datum of PTCR's volt-ampere characteristic on this basis-Least square method and nature sample function method.Compared with the method of software origin,they fit the data very well,what's more,the curve drawn is more smooth,more close to the reality V-I cuvre than by Origin.
