Ohm’s law is easy. For a linear resistor, the current through the resistor is proportional to the voltage applied across it. The proportionality constant is the reciprocal of the resistance value in — no surprise — ohms. That’s just a fancy math way of saying I=E/R where E is voltage, I is current, and R is … See more While that seems obvious today, in the 1800s, not so much. There had been some awareness of electricity dating back to ancient Greece. However, until 1800 when Volta created the “hydro-electric” battery — meaning it was a … See more In 1825, Ohm announced his formula to the world in a paper entitled, “Preliminary Notice of the Law According to which Metals Conduct Contact Electricity.” Not exactly a click-bait title. However, there was a problem: the … See more You would think that everyone would be happy to see Ohm’s law and would start to apply it immediately. That didn’t happen. Science was skeptical then — as you might argue it still is — and the establishment of the … See more The problem was the battery.

WebPile Life/Corrosion. In most conditions, provided the top 2 metres are galvanised the pile life will be in excess of 100years. Where the soil resistivity is less than 10 Ohm– further steps must be taken. This means salt water, wet peat and where soils are subject to saturation.
