In practice, Vab is used as the measure of temperature, which is introduced to the circuit through a temperature sensor modeled by the voltage source VS2 in series with RS .
Figure P3.23 represents a temperature measurement system, where temperature T is linearly related to the voltage source VS2 by a transduction constant k. Use nodal analysis to determine the temperature.
VS2 = kT k = 10 V/?C
VS1 = 24V RS = R1 = 12 k?
R2 = 3 k? R3 = 10 k?
R4 = 24 k? Vab = ?2.524 V
