Earthed physics
WebThe outer sphere is earthed and the inner sphere is given a charge of 2.5 µC. The space between the concentric spheres is filled with a liquid of dielectric constant 32. Determine … WebAllow the sphere to spark to a neighbouring earthed sphere, and then direct to earth by a wire. Teaching Notes The potential difference between the dome and the earth can be 200,000 volts, enough to make a spark jump across a narrow air gap. However, the total charge is so tiny that you only receive a small shock if you touch the dome.
