Hints for practice test 2 (Word document)
You may use a print-out of the formulas linked above during the test. You also will be given a copy of the list of fundamental constants found on the front inside cover of your book and a copy of the list of conversion factors found on the rear inside cover of your book. Any material properties such as the density, the dielectric constant, or the resistivity, that you may need to solve a problem will be given to you. Bring a calculator.
