Description: In this lab, students investigate the shapes of the actual electric fields from several different charge configurations. A good way to visualize an invisible phenomenon. Also an introduction to semilog graph paper, another invaluable tool.
Writeup: we perform Cioffari lab #24, or an online version modified from Dunwoody's procedure
