C.2.1 The ‘Earth’ for Reference
Figure C.1: Think of the Earth as a Ground.
As you know, the EARTH cannot be conductive. However, all build- ings
lie on, or in, the EARTH. Steel, concrete and associated cables (such as
lighting arresters) and power system were connected to EARTH. Think of
them as resistors. All of those infinite parallel resistors make the EARTH
as a single reference point.
