Chapter 20: Q74PE (page 736)
A certain circuit breaker trips when the rms current is 15.0 A. What is the corresponding peak current?
Short Answer
Value of peak current is \({{\rm{I}}_{{\rm{max}}}}{\rm{ = 21}}{\rm{.2\;A}}\).

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?
