Win Hill: Inverse Marx Generator ??

It's conserved in some circuits, such as caps and resistances in series with no shunt paths, like Jim's ancient riddle (or is it ancient Jim's riddle?) It's not conserved in other cases, like my inductive energy transfer example, or when you just plain discharge a cap through a resistor.

That's not vaccillating, that's the way the world is. As I've said all along.

Energy is conserved. You can count on that.

What can I say, but be careful about using "conservation of charge" in circuit design? Maybe Jim will publish his mathematical proof that charge is always conserved in electronic circuits. Let's give him a few more weeks to work it up.

I see...

More dancing.

What I was specifically referring to was your statement, above:

"Yup. Energy is conserved in the restacking-the-caps case, but charge
isn't. That was my simple point all along. Thanks for the
confirmation."

Is that still your opinion?

Do you charge batteries in coulombs? Lots of people use amp-hours.

From your power utility, do you get billed in joules?

Yup. If you put 1 coulomb into a circuit, make a zero-energy rearrangement and then discharge it, and you can't get a coulomb out, I can't see how you could derive anything useful, or safe, from the idea that charge is conserved.

Energy is conserved. That's useful.

No. One charges batteries WITH coulombs.

And that would equate to 3600 coulombs.

Note how that number has significance with our time base, then consider why.

No, we get billed in dollars. FOR what is essentially joules.

It is getting to the point where they'll bill us dollars for millijoules. The greedy bastards.

In essence, yeah, since one fills them up with as many electrons as
are needed to reverse the chemical reaction that happened when
electrons were extracted from it, plus about 10-15% more, since
there's no free lunch.

What do you want from AlwaysWrong?

A milliampere-second still does not mean that a milliampere flowed for a second, AlwaysWrong. You're wrong, as always.

You're always wrong, AlwaysWrong.

We all understand that you were born that way, AlwaysWrong.

Bullshit. If the light is on, it is emitting energy.

Period.

A noble aspiration for one in your sandals, but pray tell, what makes you think he actually HAS an Elephant? Have you worked for him before?

Did you miss the part about the box, and the flashlight it contains, being a closed and isolated system? Art

If the light is on, it is adding heat to the box.

Actually, over here we do, they base gas and electricity bills on the energy used over billing period, so gas of different types (say propane bottled gas vs piped natural gas) has a conversion factor applied to produce an equivalent Mj consumed amount ;) Gas bills had that Mj conversion factor stated as long as I remember.

So, yes!

What, you have some different definition of 'discharged'?

He's not always wrong, and I don't understand why you guys don't cut
him some slack.

Here lately he was talking about easing up on his rancor, and he even
asked a couple of questions neutrally, but all it seemed to gain him
was more hostility.

It's not like he doesn't want to be here, so if he makes mistakes,
like we all do, why not just correct them, graciously, in order to
help him see where his errors lie instead of just beating him up for
making them.
