In the 1st circumstance, if soil is of normal resistivity, the resistance of a correct grounding electrode might be envisioned to be under 50 ohms, and two these connections to floor on a little rectangular creating are already uncovered by practical experience to be sufficient. Underneath these favorable circumstances, offering enough usually means to dissipate the Electrical power of the flash with out chance of significant harm is an easy make a difference. In the 2nd case, It could be difficult to create an excellent ground link within the standard feeling in the term, simply because most forms of rock are insulating or at the very least of higher resistivity; hence, to be able to attain a powerful ground, much more elaborate means are important.
