The experiment examines the electric filed on the surface of plates covered uniformly with low-conducting coating. Each plate has imbedded over the coating a pair of high conducting shapes (electrodes). You will experiment with three configurations: two circles, a circle and a segment, and two parallel segments. Required:
Give a list of the three configurations in descending order of electric field uniformity in the area between the electrodes, i. e. first is the configuration with most uniform electric field, last is the one with least uniform electric field.
