Q & A: lemon math

Q:
I understand that putting lemon batteries in series will increase the potential, or voltage, but what effect will putting say three series parallel to one another be? Also, if I know how many lemons I need to get the voltage I want, and how many lemons I need to get the amps I want, how do I figure out the relationship between the two so as to setup them up in series and parallel?

A:
Putting three in parallel will triple the amount of current that can be delivered before the voltage starts to drop much.

If you need say 3 in series to get enough voltage, and say 10 in parallel to get enough current, I'm afraid you will nedd a pack of 30 (3x10) to get a usable battery.
