Well I do know that solar cells can do this. I'm trying to counter the claims of some products out there that say that b/c they're made of this or that they emit negative ions. For example, can a quartz crystal just sitting there emit negative ions? Not being stressed or pulsed.

Will more negative ions emit from an object (like a "negative ion generator") due to heat or piezoelectric effect or will they emit any way? Also, do certain objects give off more negative ions than others?

TY Darwin. I have referred to that wiki page often for the Right Hand Rule. I would love to get that book you recommend. Does it have a good simple battery diagram that also labels the anode & cathode. I can't imagine that we don't have a simple go-to well-labeled diagram for a battery...

Now I'm back where I started when I posted this. Totally confused.:confused: All the diagrams I've found show the electrons flowing the same way as the one I've linked above with the cathode labeled as the positive terminal. Are you saying they're all wrong? Can someone post a correct...

Now I'm confused again. The diagrams (including the one in the above link) have the positive terminal labeled as the Cathode.

Darwin123, you bring up a very good point. Given that, I feel the writers should give us qualifiers when describing current (& heat for that matter). Since you've brought it up, how does the right-hand rule play into this concept of current? I like to tie it all together.

Thank you for your help!

Ah! Yes. And herein lies the reason for my confusion. I supposed I'm referring to electric current then but the diagrams are, of course, showing electron flow (which is opposite). Is that correct?

Just a bit confused & I am in need of a simple explanation of how energy flows in a battery. This was my thinking: Cathode: positive terminal, current flows OUT Anode: negative terminal, current flows IN Is this correct? And if so, why do many battery diagrams depict energy flowing out...
