It's an exponential function on the W=CV^2
let's say initially:
C = 1
V = 16
W = 1 * 16^2
= 256
When the Voltage is split between the two capacitors, the voltage drops in half from 16 to 8, but because there are two capacitors you count them twice:
W = CV^2 + CV^2
C = 1
V = 8
W = (1 * 8^2) + (1 * 8^2)
= 128
Where did half the energy go? People are saying it's loss in magnetic radiation during the transfer. But on paper it still seems counter intuitive, so it's called a, "paradox," instead of just how an exponential function works. Something in the universe makes the energy levels exponentially higher as voltage increases. More electric pressure (V) = exponentially more energy. Cool!
