Chapter 20, Problem 23CQ
Some surgery is performed with high-voltage electricity passing from a metal scalpel through the tissue being cut. Considering the nature of electric fields at the surface of conductors, why would you expect most of the current to flow from the sharp edge of the scalpel? Do you think high- or low-frequency AC is used?

The basic mechanism of acceleration is relatively simple and can be illustrated in the following example.
