I'm using PV cells to energize an air core coil. Is there a method in which I can determine the maximum length of 32 gauge magnetic wire to use, so that I don't use too few windings and burn the coil out or too many windings limiting its' potential. I'll be using 2 PV cells that are each rated at .180ma, 1/2v and hooking them up in series to maximize the amperage. So if I understand this correctly, hooking these up in series will give me .260ma at 1/2v. How do I use Ohms' law, V=IR to figure this out?
Thanks
