The example below is for a perfect lossless circuit with no resistance for the sake of illustration only. In reality this does not exist, but again the purpose is for simplicity.
If there is 1 Joule of energy stored in a capacitor and then that capacitor is connected to a coil to transfer and then store the 1 Joule of energy into the coil's magnetic field, is this work done and if so how much work was done?
Taking it one step further, once the 1 Joule of energy is fully stored in the coil's magnetic field it then has to go somewhere. It then collapses and a diode is used to redirect the 1 Joule of energy to charge another capacitor.
What is the total amount of work that has been done in storing energy starting from the 1 Joule of energy stored in the first discharging capacitor, which is then stored in the coil's magnetic field, and then lastly ending up as stored energy in the second charged capacitor?
