MH's ideal coil and voltage question

[Pirate88179]

So, just to be clear here...

I can have an ideal voltage source that puts out 4 volts @ 1 amp but then, after 2 seconds, puts out 10 volts at .5 amps
and later, after 20 seconds puts out 2,000 volts @ 500 amps?

Do we need ideal circuit breakers that do not blow when working with this ideal voltage source?

Honestly, this just completely blows my mind that you (meaning anyone) can just make up some hypothetical device and then assign it ANY operational parameters that you want and then, do an "experiment" with this made up device and then claim that something real was learned?

This sounds like the same crap that Mythbusters might use.  I just listened to an audio book that mentioned the Mythbuster's show where they "proved" that Archimedes did not have a death ray.  They tried it, it did not work so this was PROOF!

Well, some boys over at MIT did a replication and....boom!  It worked as it was supposed to.  Those idiots at Mythbusters were ALWAYS changing parameters and then claiming devices to be "impossible".  So, they could not find a mirror large enough so, they substituted a bar of soap instead...didn't work...see?  Impossible! (Of course I exaggerate here a bit, but not too much)

I apologize...I just can not get my head around making crap up to fit your theory, and when your theory works claiming a victory.

I must be getting old.

I don't know what an "ideal voltage" is and I think that MH does not know either.
Perhaps you had an "ideal voltage source" in mind.

If "yes, then consider these questions:
Does an "ideal voltage source" need to output a constant voltage all the time?
Can a voltage source still be ideal if it outputs an alternating voltage ?

I think that I can solve the mystery for this one.  It took me a few hours to get it.

Verpies is splitting hairs on semantics.  What does "ideal voltage" mean vs. "ideal voltage source?" i.e.; How do you define an "ideal beauty?"  Is there an "ideal voltage?"

So Verpies was not suggesting that I did not know what an ideal voltage source is, even though I myself thought the same at first.  His posting is driven by looking at Wattsup's prose.

Does an "ideal voltage source" need to output a constant voltage all the time?

NO and YES.  But how many ideal voltage sources can dance on the head of a pin?   

Coles Notes on this subject will be available in six weeks.  I looked them up and if you are not Canadian you may have to look them up too.  The Americanized version is now called CliffsNotes.

But how did they get to the moon?  Answer:  Lunar orbit rendezvous.

There is a great documentary, I think it's a Nova.  I did a quick check but I don't think I saw it on YouTube.  It's all about how the NASA scientists in the late 1950s and early 1960s were struggling to design a system that would get men to the moon and back.  Typically, the solutions relied on massive rockets that would go to the moon, land, and then blast off and then go back to Earth for a standard reentry.  The launch system to do that had to be humongous, say five times the size of a Saturn V rocket.

There was a lower-level scientist that had the idea for lunar orbit rendezvous.  He could not get anybody's attention and was ignored for a few years, nobody took his ideas seriously.  Out of frustration he sent off a letter and bypassed three levels of management to make his case and get the attention his idea deserved.  That's how they ended up choosing the system for getting to the moon.

What's the point?  The point is the scientist conceived of the lunar orbit rendezvous plan all by himself, in his own head.  He did an entire successful moon mission in his head based on hardware and software that didn't even exist.  Then he took out his napkin and started doing some basic number crunching to confirm that what he had conceptualized all by himself was doable.  It's a great story about a true unsung hero.

What is the escape velocity for Earth?  You can figure that out on a blackboard by writing down a few equations.  You don't have to build a rocket and find out by trial and error.

C'mon yourself. Your question about whether MH knows what an ideal voltage source is, is absolute bunk.

I never posed a question whether MH knows "what an ideal voltage source is".

After that it seemed you were the one that was lost.

Just go back and read exactly what I wrote.  Read every word, understand it and come back to me with an apology.

I still don't think that MH knows what an "ideal voltage" is.  Do you?

I certainly don't.  But I do know why Mona Lisa is smiling.
