Electric Displacement Around 1837, Michael Faraday, the director of the Royal Society in London, became interested in static electric fields and the effect of various insulating (or dielectric) materials on these fields. He constructed a pair of concentric metallic spheres, the outer one consisting of two hemispheres that could be firmly clamped together. He also […]
