Energy added to a pre-charged capacitor or released by partially discharging a capacitor. Here, added energy is positive, released energy is negative. You can calculate the change of energy stored in a capacitor knowing the capacitance, the initial voltage 1 and final voltage 2. You can also calculate how the voltage of a capacitor with a known capacitance changes by storing a given amount of energy in it or releasing a given amount of energy from it. E = ½ C.(V22-V12) formula.

Capacitor Δ energy formula says:
•Discharging a 500uF (five hundred microfarads) capacitor from 12V (twelve volts) to 6V (six volts) releases 27mJ (twenty-seven millijoules) of energy.•Removing 27mJ (twenty-seven millijoules) of energy from a 500uF (five hundred microfarads) capacitor will lower its voltage from 12V (twelve volts) to 6V (six volts).
