    Calculating Earth Well Resistance

    dear Studiot thank you for your attention as you mentioned,the resistance of earh well depends on some variable parameter. but if we Know resistivity of soil(ρ) ,we can calculate the resistance of some Earth electrode,such as copper Rod . NOW, I can't find any formula in any code that...

    Calculating Earth Well Resistance

    HI ALL I am bored! I am searching about Earth well resistance calculation for 2 weeks and I can't find anything! when I speak about Earth Well , my mean is one Well about 4 to 6 meters that we put a copper plate in it.one stranded copper wire connects to plate and the other End of wire...
