batteries that make cents

Postby Aldiet3 » Mon Dec 23, 2013 6:57 am

My daughter was comparing voltaic piles. One pile had 6 pennies and 6 dimes
The other penny had 6 pennies and 6 quarters
When hooked up to the voltmeter they had approximately the same reading. Is that correct?

The project also requires future applications. I believe they would light up a red LED light but that is it. What would a future application be? Thank you
