Stray or ghost voltages occur from capacitive coupling,
which takes place between energized circuits and non-
energized non-connected adjacent wiring.
practical occurance : When facilities or buildings are
built and wired, it's very common for the electricians to
pull extra wire thru the conduit for future use. These
wires are typically left unconnected until needed.at this
situation coupling effect takes place as explained above.

Given a collection of points P in the plane, a 1-set is a point in P that can be separated from the rest by a line; i.e. the point lies on one side of the line while the others lie on the other side. The number of 1-sets of P is denoted by n1(P). The maximum value of n1(P) over all configurations P of 19 points in the plane is 18
