Do you understand how the graph posted on Friday was interpreted in light of Millikan's oil drop experiment? That was our first order of business. Next we revisited the idea that the slope of a V vs x tells us the strength of the electric field in the region from which we measured the potentials. Be sure to distinguish between "potential" and "potential energy." The are different from each other, but they are important each in its own right. So far as our class is concerned, electric fields do two things:
We also introduced more formally "equipotential lines": At which point, A, B, or C, is the strength of the electric field greatest? weakest?
