Okay so I have conducted an experiment to find the internal resistance of a battery pack by gradient of a graph of voltage against current. All so far okay. I went on to find the EMF also, again all so far okay. Now I need the short circuit current, and I cant find any information anywhere unbelievably. I don't know if its known otherwise elsewhere. But anyway, I thought it would simply be EMF/Internal Resistance. The battery pack is in series with 4 batteries, it is not parallel. Can anyone confirm/disprove this for me?
