Definition of electrical ground
WebCircuit common is considered to be a separate concept, with the symbol . My understanding is that "ground" means that the node can and should be tied to the earth. "Common" implies an arbitrary voltage reference with no connotation about its voltage relative to earth. One might have multiple commons in a schematic, but earth is earth. WebMar 7, 2010 · If the second ground rod failed to give sufficient resistance (or lack thereof), a third was put in, and this, (three rods), was always deemed "grounded". Ground can be a variable definition, depending on what organization is doing the defining. My definition of ground, is an electron reservoir able to take OR give electrons.
