I am working with RTGs right now. I want to hook two of them up in parallel to charge a battery. Basically, the setup I had planned is like this: http://img339.imageshack.us/img339/9549/rtgparallel.png [Broken] I am trying to determine the power, current and voltage that would be given to the battery. I have been trying to research and know about Kirkhoff's laws. However, do they work in this situation when the RTGs have their own voltage and current? For reference, the RTGs both have a current of 0.248A and a voltage of 13.89V. How do I calculate what is given to the battery? Thanks!
