OK, so I've been looking into the possibility of using some super caps in some personal projects instead of batteries, just for fun. In my research, it seems that farads is a measure of electrical charge, and to convert to Wh or Joules, the voltage has to be squared. I've found online calculators to input voltage and farad rating and get a Joules output to get a "total amount of energy stored" comparison. So because voltage is squared, when I'm using capacitors in series, I have to calculate the Joules of each capacitor and add them together, right? So two capacitors in series doesn't somehow magically create four times the amount of energy that can be stored, right? Or due to the function of capacitors, does it actually do that somehow?
