This principle offers an elegant method of finding the equivalent resistance between adjacent points on an infinite resistor lattice. In Young's famous double-slit experiment, it explains how the beams interfere either constructively or destructively at a point.  For ten points, what principle of electromagnetism states that the field at a point is the vector sum of the fields from individual sources.
