Ohm In an alternate universe, Ohm was a mad Time Lord god. Savar met Ohm whilst searching for Omega within a black hole. (PROSE: The Infinity Doctors) Behind the scenes edit OHM was also a proposed (but never used) name for Omega, as the name when rotated 180 degrees forms the word 'WHO'. Coincidentally, Ohm is a unit of measurement represented by the upper case version of the Greek letter Omega. (TV: The Three Doctors) Retrieved from "http://tardis.wikia.com/wiki/Ohm?oldid=1235460"
