What sort of circuit would I have to set up to figure out the internal resistance of a dry cell? Also, what would i need to be measuring and doing etc, to find this internal resistance?
Thanks, Jack.
Well, i know this thread is really old, but anyway, that question is more one based in chemistry rather than physics. I can't answer that for dry cell batteries, because I am not 100% sure how they work, but i can answer that for galvanic cells.
So first you have to understand how they work...
