ENGINEERING APPLICATION A thermistor is a solid-state
Chapter , Problem 45(choose chapter or problem)
ENGINEERING APPLICATION A thermistor is a solid-state device widely used in a variety of engineering applications. Its primary characteristic is that its electrical resistance varies greatly with temperature. Its temperature dependence is given approximately by where is in ohms is in kelvins, and and B are constants that can be determined by measuring at calibration points such as the ice point and the steam point. (a) If at the ice point and at the steam point, find and B. (b) What is the resistance of the thermistor at (c) What is the rate of change of the resistance with temperature at the ice point and the steam point? (d) At which temperature is the thermistor most sensitive?
