The rotational energy is used to build up static charge across the plates, while each plate periodically makes electrical contact with another as it rotates, building up a voltage by induction. The Wimshurst machine is named after its inventor, British engineer James Wimshurst (1832-1903). The American Heritage® Science Dictionary Copyright © 2011.
