Chris:

I am going to gloat a bit and you are going to eat some humble pie.  It's a little bit of poetic justice.  You should learn from this.

MileHigh - You should learn from being wrong about my question also!

OMG - MORE RULE Changing!

It is, its not, it is its not....

Again no ACCURATE RESULT CAN BE OBTAINED!!!!!!!

Now you two have proven it beyond a doubt!
You are completely FoS.  Under the hypothetical conditions MH set the answer is completely deterministic.  From 0 to 5s the current is exactly the starting current plus 3.5A/s.  Beyond 5s it is exactly the starting current plus 17.5A plus 2.5A/s.  There is no accuracy issue.

MileHigh - You're game playing and I don't like it! Its all you do.

Insults are directed at you simply because of your stupidity! Game Playing is for stupid people that have nothing better to do in their day! dt is normally considered to be a measure in time and you have again redefined the rules on the table!

You're a time waster like I said! You get paid to do it!

There is no practical benefit to being an A-Hole here! Unless you get paid to do it!

I am no longer playing your games, play your games with MarkE and TinselKoala - Try kiss n Catch first you may find a new hobby!

Bullshit.  There were no games.  No rules were redefined.  I gave you a perfectly legitimate question.  You look stupid now.  Don't you give me that bullshit about getting paid.

You were the asshole, no doubt about that.   You couldn't solve an electronics question for a circuit with one lousy component.  Think about that next time you are on the bench and ask yourself, "What am I really doing here?"

You are running away now?

MileHigh - You know I am already eating Victory Pie - I already was right about your question!

Your equation will change depending on the Inductor.

2 Henrys with 7 volts is not enough information to get an accurate answer! If the inductor is 4m x 4m square, it will give a totally different current to 10mm x 10mm Inductor!

Your answer to your questions Only Gives An Approximation!

If you think this is an accurate answer you're fooling yourself!

You changed the answer you were looking for half way through the test simply because you again underestimated me - Your best ability is making Assumptions!

YES SIR - you are playing Games!

Games that you change to suit yourself, when you need to!

You are just showing that you are clueless now.  I didn't change a damn thing.

No Bill - this is my way of saying that if you take my legs I cant walk.

So if you think you're really smart now - You are still not!


What part of "I don't know the answer either..." in my post did you not understand?

I am intelligent, I am not anywhere near as educated in the electronics field as these guys you are arguing with.  Electronics is one of my hobbies, I have only been studying it for the past 7 years or so.  I have learned a lot from these fellows, which I greatly appreciate.  I know a lot more now than I did even a year ago.  It is a process, a learning process.

When you think you know it all, you stop learning, and that is sad for anyone.

Tinman has a lot of respect on here and is capable of debating his points.  He has said that he respects the knowledge of these other fellows you call idiots.  He just does not agree with them in this one certain area.  They also acknowledge Tinman's work.  They can debate, which is good for everyone.  In the end, someone will be right, and the other mistaken but, that mistaken person, or persons, will have learned something, as will have all of us watching over here.

Take a lesson from Tinman and debate, not argue and name call, and you might just learn something from these other fellows as well no matter who turns out to be correct.

No - staying right here, just not playing your GAMES! DO you deny that the equation you presented is ONLY an Approximation?

Admit it!

So I guess that is a big no then.  You did not understand right?

Good to be able to admit that.

Bill

PS  I not only read the post, I copied it for you in my question.  I tried to make it easy for you.

Thank you.

Pencils down.  The answer to the problem as stated is readily solved as below:

I from 0s to 5s is:

I0  + 3.5A/s

I beyond 5s is:

I0  + 17.5A + 2.5A/s * (T-5s)

Mark - I will say, this is perhaps the most constructive post on this thread!

Well Done! You too now deserve a wee sleep  ;)

You know, I have just the slightest little bit of respect for you now - You put MileHigh to shame here in one post! Well done!

You have shamed yourself.  Contrary to your claims, the current function versus time is easily determined.  It does not depend on the inductor package or any of the other red herrings that you threw out.  It depends on the integral of V/L dt as MH posted.
