It is decided to electropolish a complex cast copper sculpture, because the surface is too complex for mechanical polishing, and the as-cast surface does not have the required appearance. Through experimentation with piece of copper, it is found that a current density of 1 A/cm2 produces the required appearance. It is estimated that the entire surface of the sculpture is 100 cm2 , and it is decided to electropolish the sculpture at 100 A of current. No more than 0.0001 m of copper should be removed from the sculpture, so that the design shape is not altered. Determine the maximum time for electropolishing if the process is 100 % efficient?
What will be an ideal response?
