Reading:
In the Hambley text, continue to
study Chapter 2, Sections 2.1 through 2.5.
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
R_{sensor}
is a thermistor whose resistance is 1000 ohms at room
temperature and 5000 ohms at body temperature. If R_{1}
has value 500 ohms, what is the value of the voltage Vsensor at
room temperature and
at body temperature? What is the difference in
V_{sensor} at the two temperatures?
Extra Credit:
What value for R_{1}maximizes the difference
in V_{sensor} at the two temperatures?
