Yes, ripple is AC leakage into what should be a pure DC current and 
     can adversely affect plating if too high.  Ripple is measured by AC/DC 
     of the present setting and usually decreases as the rectifier is 
     turned up.  As a general rule, Max. AC ripple should not exceed 5%.

Is it true that rectifiers generate a constant minimum AC voltage (rms) 
that causes variable ripple depending on actual or overall voltage?  In 
explanation, is ripple defined by the minimum AC voltage over the rated 
output voltage only?
     
Could the group enlighten me on the subject of minimizing ripple and how 
it affects plating?  There's been much discussion about copper plating, 
and I would appreciate some information on this topic.
