Joule Thief 101

[MileHigh]

Here is a bit of news for you MH.
The shopping cart is not pushing back at you with exactly the same force,as if it did,it(and you) would not move--how about that?. The shopping cart losses some of that force to motion--think man.

So there is your big fail right there.

f = ma

Force = mass x acceleration.

What do you have to say now?

Well Brad, you are still stuck in your rut I see.

Here is a little story for you to contemplate.

You go to the supermarket to shop for food.  You get a huge amount of stuff and your shopping cart is very heavy.  You are stopped, and then you push on the cart with a continuous even force.  How about that - the heavy shopping cart is pushing back at you with exactly the same amount of force.  You also notice that the shopping cart is starting to speed up and you have to keep quickening your pace.

Think about this:  What if the shopping cart was a "magic" 22nd century shopping cart and instead of being on four wheels with bearings, the shopping cart floated one inch above the floor through magnetic levitation.  That means when you push on it it glides frictionlessly across the floor.

Think about this:  Imagine the shopping cart is stopped, and it has infinite mass.  Then, you push on it and then no matter how long and no matter with how much force, the shopping cart doesn't budge an inch.

Can you learn anything from this Brad?

More stories: Jammy!!


But above: UpHill, or .............  without bearings?

Brad:

No avoiding this:

<<< In one statement you say a voltage cannot exist across an ideal inductor while a DC current flows through it,but your question states an ideal voltage of 4 volts is across the ideal inductor while a DC current flows through it. >>>

What are you talking about?  I never said that.

No avoiding this:

Here is the reality for you Brad:  You have myself, Poynt, Verpies and Partzman telling you how an ideal coil works and we are all in agreement.  What do you think Picowatt is going to say?  And what is your response to the fact that we are in agreement although we still haven't heard from Picowatt?

<<< Of course MH will try and skip past this,as it dose not agree with the answer he wants everyone to believe.  >>>

Go ahead Brad and tell us about this: "Wouldnt the magnet floating over the super cooled superconducting disk, block, whatever it is, be a perfect example of ideal cemf producing an equal opposing field in order for the float to happen?"

So you are suggesting that this is like applying voltage to a ideal coil and no current flows?  This is not my claim, apparently you agree with Magluvin's statement.  Please go ahead and explain how these two things are equivalent.

No avoiding this:

I said to you if you didn't like the ideal inductor, then turn it into a real inductor by putting a 0.00001 resistor in series with the ideal coil and then go and answer the question.  I don't care if you want to do that, and now just go ahead and answer the question.

Personally, when I first asked you this I think that you were incapable of answering the question and so you just brushed it off.  I am still waiting for you to answer the question and do it with a real inductor if you want.
