** Changed to Wednesday, Feburary 18 **
In the Hambley text, continue to
study Chapter 2.
We will focus on Sections 2.4 (node-voltage analysis)
and 2.6 (Thevenin equivalent circuits) this week.
We will not discuss Section 2.5 on mesh-current analysis in class.
Please read Section 2.8 on the Wheatstone bridge before class and
lab on Wednesday, February 11.
- Please solve the following problems at the end of Chapter 2
in the Hambley text.
2.28: In this problem, you are designing a voltage divider, and the
"device" will be connected in parallel with one of the resistors in
the voltage divider.
The smallest voltage (4 V) appears across the device when it draws the
most current (25 mA), and the largest voltage (5 V) corresponds to the
least current (0 mA). Briefly explain why the voltage supplied to the
device is not constant.
2.31, 2.32, 2.34, 2.38
Please submit your lab notebooks on Monday, February 23, in class.
I will review your notebooks for Labs 1 (there is not much for this one),
2, and 3.
I will not review Lab 4, which we will perform on February 18.
Please follow the
Laboratory Guidelines that are available on the course web page
when preparing your notebook.
