MH's ideal coil and voltage question

[tinman]

Good question - I don't know. The scenario you paint seems a bit like those dastardly 'which came first, the chicken or the egg' situations
Will have to sleep on that.
Cheers

Indeed
Perhaps Poynt,PW,verpies,and the likes,will give it some more thought as well,instead of falling into the world of MHs endless garden paths.

I really do love that saying of verpies-->just because everyone else makes mistakes,it dose not mean we have to.

Oh i see lol.

I say the very same thing as Poynt did,but i get a totally different reply.

To gutless to treat Poynt like you treat me?
Oh,and here is the kicker--the guy(me) that you think is such an amateur,and knows so little,gave the very same answer as Poynt,who is very well versed in EE--only i gave it first.

This speaks volumes about your true nature MH--your pathetic.

Brad

First of all, I don't know which posting you are referring to.  Secondly, kiss my ass.

Kiss my ass because Poynt made a long posting where he started to move significantly in my direction and your response was quite polite.  If I had said the same thing you would have said I lost my marbles and used a lot of other colourful expressions.  You were too gutless to treat Poynt like you have treated me?

In other words, your behaviour would be exactly the same as what you are accusing me of.  Here is where you can actually apply the term "hypocrite" to your own behaviour.

You are a hypocrite Brad.

i.e.;

And to think,you thought you had the smarts to give EMJ a hard time on his understandings about inductors and coils--and me for that matter.   <-- This one sounds like a rude insult.
You have yourself a great time MH,but i am done with your repeated stupidity,and re-writing of physics.  <-- this one sounds like a rude insult
I think you are a little lost when it comes to understanding what CEMF is in an inductor-or anything for that matter.   <-- This one sounds like a rude insult
Yep-you have finally lost your marbles.  <-- This one sounds like a rude insult
MH is just lost again.  <-- This one sounds like a rude insult

However, Brad, you might or might not know how after the fall of the Soviet Union in America they talked about the "peace dividend."

Well, let's say you got the "war dividend."  You can be so unbelievably obstinate and your knowledge was so screwed up and so skewed that you were hopelessly trapped in a backwards electronics pre-kindergarten.  You had to be battled with over and over and over to force some sense into you.  You still have a long long way to go.

You had to get your ass kicked over and over.  You were kicking and screaming all the way.  You still have a serious mental block about admitting that you are wrong.

Nonetheless, you have progressed more in the past three months than you progressed in the past six years watching pulse motors turn.

Don't believe me?  Just go read this thread from the very beginning and read yourself and what you have to say.  So for you, being told straight to your face by me that what you just posted was idiotic and completely and totally wrong who knows how many times was ultimately for your benefit.

Just go read the this thread from the very beginning and see how completely idiotic most of what you say is from your current perspective.

It's like very Old School schooling where knowledge had to practically be beaten into your behind.  And there is no way in hell I would keep this up.

Like it or not, you are 10 times smarter when it comes to electronics than you were three months ago.  And you still need to lock yourself in a room for a month and read and understand some books on basic electronics so you will stop dropping outrageously ignorant and stupid comments that make it look like you were born just yesterday.

I think what this is saying is that the Vsource is NOT the same V that the inductor sees,, the inductor is going to see Vsource-VdropR and so VdropR becomes the EMF that the inductor matches with CEMF,, and since Vsource is larger than VdropR+(CEMF=VdropR EMF) current will still flow.

So the CEMF from the inductor is less than EMF from the SOURCE because the inductor sees the EMF from the RESISTOR and NOT the source.

That's right.  And if I was going to split hairs I would say, "the EMF from after the RESISTOR."

I really do love that saying of verpies-->just because everyone else makes mistakes,it dose not mean we have to.

Brad

Exactly, so when is this mass hysteria about Kirchhoff's voltage law going to come to an end?

[MileHigh]

This one is for the KVL hysterics.

Let's switch over to the physical world and discuss the bloody frictionless fully-loaded shopping cart.

Look at the attached graphic.  This time we are going to use the Force-Voltage analogy.  Pay attention to the variables.

You are pushing the shopping cart.  The force you push on the cart with your hands is the voltage.  The velocity of the cart is the current.  The heavy shopping cart is the inductance.

If you push on the cart with a constant force then you know that you have to start running faster and faster down the aisle because the shopping cart is speeding up - it's accelerating.

You push on the cart - that's the EMF.

The cart pushes back on you with the SAME FORCE, that's the CEMF.

"For every action there is an EQUAL AND OPPOSITE reaction."

COMMON SENSE PEOPLE, take an example from REAL LIFE and THINK.
