Re: [Phys-L] "Electric current" does not mean "electron flow"

If the goal is to exhibit positive current, please forget what I
said about electrolysis. A better example is copper electroplating
The current consists of Cu++ ions. The experiment is harder to set
up than the electrolysis experiment ... but the interpretation is
much simpler.
A reference is
http://www.woodrow.org/teachers/ci/1986/exp30.html
... but don't bother with pre-1983 pennies. Copper wire is nearly
pure copper, and works fine. Use a coil of wire to achieve a large
surface area.
