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 ??? --- End quote --- 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? --- End quote --- 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 |

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

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