Perhaps I am misreading your post, but I don't think this is correct. Condensers, what I call capacitors, do not store energy they store charge. Energy in joules is voltage in Volts times coulombs (charge) in Farads. When you connect a charged capacitor inline with a series of capacitors the voltage is transferred to the far end, but the capacitance is drastically lowered. The energy available at the far capacitor is likewise drastically lowered. I think that Franklin must have meant the voltage is transferred to the far capacitor. The energy most certainly was not. On a circuit board, an electromagnetic wave in a transmission line looks like it is traveling through a network of inductors in series and capacitors in parallel. I am not going to speak to the subject of photons because that is beyond my training. But the fact that free space has a permittivity (capacitance in Farads) and permeability (magnetism in Henries), implies the relationship is the same as on a circuit board. Inductors in series and capacitors in parallel. If you meant that the capacitors were in parallel, then voltage lowers (v=v/n) (is distributed) and capacitance increases (c=c*n) and the energy is available at the far capacitor. But not without constraints. It is normal to talk about both capacitance and inductance when discussing electromagnetic waves, and Franklin was certainly not doing that. He was not discussing waves, but static charges. The energy is not transferred to the far capacitor, it is still distributed through the chain of capacitors. The model of a chain of series capacitors does not describe the photon. Please correct any errors in my thinking.
