Answer Posted / tauseef tarique, engineer(e)
The earth resistance value can be checked by the use of
earth resistance tester (called megger earth tester). The
best earth resistance should be less than one ohm but the
permissible value is less than 5 ohm. For rocky areas it
should be less than 8 ohms.

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
