Orcad Pspice Tutorial

Free CircuitMaker software. Similar to Orcad (and it's easier to use, but has fewer features.) Version 6. You can no longer download a free version from the company. This is an old version I had a copy of.

All About Circuits An outstanding open-source online textbook on electric circuits with lots of practical stuff explained really well. Read Volume 1 - DC as soon as you can. Volume V - The Reference is also full of great stuff.

Some Lecture Notes (Note: view these in Internet Explorer for best results):


Lab 1  Due Monday April 23rd. Note that our mystery resister is actually not very mysterious--it is the big bluish colored resistor. Also note that you will not be able to get Vb = 4.85 volts. Just pick two of your resistors that get as close as you can.

Lab 2  Due Monday May 7th. Note: Some of the calculations refer to techniques you will be learning in Chapter 4. You will need to get a few more parts from me as well.

Lab 3  Due Monday May 21st. Don't wait until the last minute to do the lab! You can use an AA battery instead of an AAA battery if you want. Ignore the note that says use a 10k resistor instead of 8.2k. use the 8.2k.

Lab 4  Due Friday June 8th . Don't wait until the last minute to do the lab!
