The steel culvert in itself constitute a rather massive ground stake. The concrete is conductive so, yes, you can say you have a Ufer ground. With that very wet (high water table) land I can only ass

From the dictionary: There is no need to go any farther. Forget your calculations, this is the definition. Electrical resistivity quantifies how strongly a given material opposes the flow of electric

It was written... Of course there is. But it ISN'T the units of bulk resistivity. But how about "What is the resistance per unit length of copper wire to be used in winding a transformer?" Ohm*meters

Yes, I agree, there's no "ohms/meter" Of course there is. But it ISN'T the units of bulk resistivity. But how about "What is the resistance per unit length of copper wire to be used in winding a tra
