After all is said... The only thing that flows through an Electrolytic... Is AC. With DC once equilibrium is reached the only current that flows is leakage current.

As used in arduino, I think of caps having current flow into the positive side from the power supply at a steady rate, and out of the positive side in bursts to power transients in the other circuitry.  The minus side is just a reference.

Using caps in, say, audio circuitry, may call for different thinking.
