Copper Zinc Tap Water Fuel Cell

@all
Perhaps some of you need a good laugh today at the expense of a newbie.  I humbly offer myself to you.  I want to make certain that any results posted on these galvanic cells have been performed correctly.  Attached is what I think should be the correct measuring method with my multimeter.  Would a kind member please confirm or reject this?
Thanks â€" Brad S

Your drawings are correct by my electronics training:  Measure parallel for voltage and in series for current.

We all start somewhere as beginners; no need to be embarrassed.

I believe old water heaters have a sacrificial anode made from magnesium, that woul be a good find. I have an old one at kicking around perhaps I'll give it a try! Forgive my ignorance but aren't pencils made from graphite?

Yes, linearfashion, this would be correct.
Bill uses a magnesium water heater anode for the negative electrode for his earth battery.
Pencil leads are graphite. My hardware store gave me a plumber's pencil with a fat and flat carbon lead.

This is a copper zinc thread.

Lasersaber opened a magnesium/carbon thread which he called air battery.
It is getting confusing around here with all of us cross-posting different metals on different threads. (me included  )

So, have a look at the air battery and join in the fun.

thank you,

hi all, a little update.... very little (if any) corrosion has occurred on my setup (see very first post)...... i got a little distracted with making a lead battery hehe..... ill post some update pictures of my original copper zinc setup later today.
