I say 144mJ delivered by source = 72mJ as heat in the wires + 72mJ stored as electrical energy.
You say 144mJ = 72mJ as heat in the wires + 72mJ work + 72mJ stored ???

You didn't read what I said. You must learn to read.
Energy = Heat + Work
144 mJ (Energy) = 72 mJ (Heat) + 72 mJ (Work)
It's not complicated, is it?

You're incredibly patient. I don't quite know what dacus's problem is, but he's long past the point of entertaining for me.
It's like telling him that it takes time to charge a capacitor and he replies that time is not energy. :-// |O :-DD

So there is no stored energy ? A 1000uF capacitor with 12V across contains no stored energy ?
What did that work you are talking about did ?

The battery. Those electrons didn't just get into the capacitors by themselves now did they?

Losing half the energy as heat is not enough ? You can say they went downhill.

It's fascinating seeing how many different ways he can come up with to argue that black is white, but yes, it does get boring after a while.
