Current study deals with the room temperature conductance of Graphene Sheets as a function of their binding energy and lengths. The structural properties of each sheet were calculated after the relax of the structures by performing the SIESTA-trunk-462 program. The results showed that the electric conductivity is inversely proportional to the theoretical separation of the gold electrode. The increase of the angle C-C-Au effects on the electric properties of the Graphene Sheet, the Sheet is became much conductive and effectient electrically at large angles. This may refers to that the electron transmission coefficient of the Graphene Sheet depends on the type of the contact of the top gold atoms of the pyramids with the anchor atoms in the Sheet.
