Hey folks,

Let's do the test on Monday so I am there. Today work on circuit analysis with the test questions given out yesterday. Here is a link to the test if anyone needed a new copy.

Here and here are some online practice questions and/or you can check out the text book as well for some additional practice.

Have a great day and weekend.
