- Please solve the following problems at the end of Chapter 2
in the Hambley text.
2.1, 2.6, 2.8, 2.13, 2.17, 2.24, 2.25.
Consider the voltage divider circuit shown below, where
is a thermistor whose resistance is 1000 ohms at room
temperature and 5000 ohms at body temperature. If R1
has value 500 ohms, what is the value of the voltage Vsensor at
room temperature and
at body temperature? What is the difference in
Vsensor at the two temperatures?
What value for R1 maximizes the difference
in Vsensor at the two temperatures?
