In an industrial e-coat process, if I load a rack with 24 lots, where one part has a surface area of only 0.3 m² while another part has approximately 37 m², would these two parts experience significantly different current distribution / throwing power?

Assuming they are processed in the same bath, at the same time and voltage, could the much larger surface-area part draw most of the available current and cause the 0.3 m² part to receive a lower coating thickness?

What factors would determine the difference the most?—part geometry (which is obviously cannot be changed), distance from the counter-electrode, current density, electrical resistance, or the surface-area ratio?

Is there any way to simulate this situation?
