Gold is a material which can be used as a conductor on circuit boards.
In a typical application a gold strip 1cm long, 0.64mm wide, and 10 m thick may be deposited on a circuit board. Preliminary experiments show that when a voltage of 1mV is applied to a gold wire 80cm long and 5mm in diameter a current of 0.99A follows. In your text there is a diagram showing the electrical resistivity for pure copper and three copper alloys as a function of temperature. A coldworked material is likely to be stronger but less ductile than a non-cold worked material. Can you design an electrical test to determine if a material has undergone previous plastic deformation.
