A characteristic of a material in which a decrease in resistance accompanies an exposure to increased temperatures.
A decrease in resistance with an increase in temperature.
A NTC thermistor is one whose zero-power resistance decreases with an increase in temperature.
1. The partial derivative of any physical variable with respect to temperature, when the value of the variable decreases as temperature increases. 2. The decrease in reactivity of a nuclear reactor with increase in temperature. Increasing temperature within the reactor increases the average neutron energy. Since the cross section of the fissionable material decrease with increased neutron energy, the net effect of increased temperature is to decrease the number of fissions.
Pertains to the relationship of resistance to temperature in a thermistor--i.e., as the temperature increases, the resistance decreases.
A negative temperature coefficient (NTC) occurs when the thermal conductivity of a material decreases with increasing temperature, typically in a defined temperature range. For most materials, the thermal conductivity will rise with increasing temperature.
