Hey guys, I need to figure out how to make a simple test circuit so I can test how much energy is stored inside various power sources (probably 1-10V, ~10mA range). I figured all I need to do to get a rough estimate of how much power these sources (they're like batteries, not continuous supplies) can provide is to take down readings of the current for a while and extrapolate down to current=0 and tell excel to make a graph and best fit equation and do an integration * voltage.
Then again i was wondering if the voltage dropping over time would play a big role in this. Can anyone suggest a circuit or other information that could help?
