Question: How is the internal resistance of a standard battery affected by temperature?
Answer: Internal resistance can be affected by many factors. One main variable, and the one I will be exploring is that of temperature.
Hypothesis-
I predict that the temperature rise and increase in the internal resistance will be directly proportional. In ideal conditions, this would be the case , however, we must remember to account for atmospheric influences and human error. It is more likely that after a steady rise, the correlation will become more and more negative, as the water bath , in which the battery sits begins to cool. Other influences, such as efficiency of the battery and the method in which it is used will also effect its performance.
Batteries conduct heat , they must have the ability to do so as they are made of metal (Zinc) and convert chemical energy...(short extract)
