MH's ideal coil and voltage question

  wattsup was just having an "off day". That's all that was up!

I know that. Your are on a sim and that sim is not simulating an ideal voltage as per the definition otherwise it would not change. Don't you get it. If your sim could simulate an ideal voltage it would have stayed at 4 volts all the time according to the definition. There is no ideal voltage in your sim. It is just simulating an applied voltage given the other parameters and it will change in time.
Actually there is no point in using a sim with an ideal voltage because you will always have the same voltage straight line.

The idea of the ideal voltage is to maintain a fixed voltage source while you can vary other parameters that cannot vary the ideal voltage but will provide you with how the circuit works when you, let's say, vary the resistance, or inductance, or impedance or capacitance while that ideal voltage always stays the same. The require gain or reduction in current will be automatic but the voltage will never change. You can then measure across different components in the circuit to see those changing values but the ideal voltage will never change. Otherwise what is the point in having an ideal voltage when it is just simple voltage.

@all

Common guys. There is process, there is teachings but there is also logic and logic has to win every time. At least this is what has been paying my great salaries for years. Nothing beats logic.

Either that or come forward and convene that this question does not require an ideal voltage source to propose the teaching you wish to promote, because it just does not click at all. It should at least send alarms bells ringing when other @members here cannot adjust to your line of thinking that maybe the teaching requires some "fine tuning".

Wattsup:

I would call that the classic ironic twist of the free energy forums.  You are supposed to be "out of the box" experimenters.  You are supposed to be "free thinkers not held back by the constraints of dogmatic science."  You mock the scientists and the engineers and say they "only know what is in books" or, even worse, they "are programmed by the Powers That Be not to think."

And then the subject of a time-variable ideal voltage source comes up.  And what do you do?  You look for a definition in a book and you stick to it like glue.  The definition says nothing at all about whether or not the voltage can vary in time but the concept is seemingly "too radical" and you can't process it so you make up a "new rule" to "fit in" to how you think things should be.

It is so ironic, it's almost surreal.  For myself, and Poynt, Verpies, Partzman and countless others the concept of a time-variable ideal voltage source was presented to us, we processed it, and didn't flinch for a second.  The simple fact is that it makes perfect sense.  The logic that describes it is perfect.

It's almost shocking that so much time and energy has been wasted on this non-issue.

P.S.:  I will just repeat that a very powerful car audio amplifier could make for a pretty beastly variable ideal voltage source.

Surreal is right.
Your thought-experiment ideal voltage source has a virtual knob on it that says "Voltage output" right? And you can virtually reach out and turn that knob up and down, can't you? Thus making a simple time-varying ideal voltage source. Replace the "knob" with whatever virtual control system is needed to vary the output on whatever time schedule you like. What is so difficult to understand about that?

[MileHigh]

Yep, you could even imagine my "wrist" had a bandwidth of about 30 kHz and could make a variable ideal voltage source that sounded like two lead guitars trading licks....
