Internal Resistance of a battery lab
I'm doing this lab where we have to find the internal resistanceof a charged and uncharged battery. We got our data by plotting a Vvs I graph, and found the internal resistance of each battery usingthe slopes of the graphs. From my graphs, I can see that theinternal resistance of the charged battery is higher than that ofthe uncharged one. Which makes sense. However, I'm having a hardtime writing the conclusion for this lab. The current increases asthe voltage decreases for both batteries, which is obvious, whatelse am I supposed to say? Any comments I can add?

Discussion and Conclusion Source of error The wire used to connect the circuit contains resistance so thicker wire should be used to reduce the resistance so a more accurate result will be obtained Precautions The multimeter should be setzero before it is used as an ohmmeter Setzero is also necessary when the scale in the ohmmeter is changed The resistance box may have poor resistance because of rusting at the contact surfaces Use sandpaper to polish all the See Answer
