Re: How much acid in bath?
No flaw. What you said is what I said. The resistance of the bath is high (becasue the acid is weak). Pure water would be the ultimate in high resistance.
High resistance means you need high(er) voltgage to get the current flowing. I=E/R (ohms law) like you said.
The fact that I'm demanding a higher current (14Asf) means I also need a higher voltage for the given acid. More than my supply likes to put out.
The only way to counter this is to lower the resistance by more square inches (more parallel paths for current to flow) or stronger acid.
