What can you use really weak electric currents for?

[WayTooSharp]

Like say it was a really really weak battery putting out a few thousandths of an amp.

They fit perfectly into the battery recycling bins located in the entrance of most electronics stores! The less charge the better!
You can also use them to just barely or not at all turn on electric things.

Meh. They don't make it easy for me? I will support future miners instead.

Haha. Like really tiny halogens.

I was thinking medical applications.

Power an old Casio watch module that's repurposed as a desk clock?

Hmm. Are those watch batteries like 1.5 v?

Or any old battery that has dipped in voltage and has miniscule current capability (hell, a coupla' potatoes would suffice):

wow. cool.

Well reading minor electricalfieldsis important to guys like hammerhead sharks . They can pick up very small electricfields of food sources hiding under the sand on the bottom !

seems to me, very low amperage is a pretty good sarcasm attractant. other than that? maybe you could hook it up to a maglite bulb? that might be brighter than a fire fly, but i'm not an electrician.
