22:5422:54, 27 June 2026 diff hist +636 N Negative resistance Created page with "Negative resistance is when a device or material allows more current to flow as voltage across it is *decreased*, or vice versa, less current is passed with an *increase* in voltage. It's principle use to to create very high speed oscillators, in the microwave range. Some natural semiconductors also seem to have this capability, Cornish arsenopyrite and wolframite seem to occasionally. In a curve plot it looks like a reverse loop, it's hard to capture as it's ra..." current

This was caused when the ancient continents of Euramerica and Gondwana collided to from the supercontinent of Pangaea. The granite that rose towards the surface under what is now Cornwall distilled many elements from deep in the earth into the existing ('country') rock in the margins around the granite. It was these areas that would very muc..."
