OK, got it now.

Yes the game is really over and for me there are just two outstanding issues:

1.  Brad admits that he is wrong about my response to the harder question.
2.  Brad gets up the learning curve and understands the original question and then answers it correctly all by himself and clearly demonstrates that he understands what he is doing.

What's been going on for the past six years?  Even The Shadow can't answer that one.  I intentionally answered a more difficult question in order to leave the original question up for discussion among the regulars.  Again, we are talking about a very simple circuit here consisting of a power source and one single solitary component.

For both Brad and Wattsup, I am not holding out much hope for either of you but there are always the high-odd payouts for the long shot bets.  You guys would be the winners, but nothing ventured nothing gained and no pain no gain.

Like I said I will always have full respect for you but it does not mean I will always agree with your methods. Why don't you just cut the high on the hog "I won't spoon feed you" slogan. I am not going to backtrack on all these crazy pages to find out what your questions are and then try to decipher changes to a question and what not. I have better things to do. But since you like and can afford to spend your days on this forum not spoon feeding but more like feeding the fire, then the onus is on you to clarify things, not on me.

If the QUESTION is as I had copied on the previous page to @tinman, then I have nothing more to say. It's your business if you want to call me this or that, I don't care.  But if that was your question and you wish to re-work the question, then do it and save us all your violin playing. Yes, you are allowed to re-work a question but it's up to you. If you are more concerned of peoples perceptions then asking a proper question, then that's your character flaw not mine.

If the question you asked is not on the previous page, then you need to post it again because I ain't searching for it. Imagine I have to wade through how many damn variables about a question to even figure out what the question is and all you are worried about is not spoon feeding anyone. Who asked for spoon feeding? Start by just getting the table set properly before you invite anyone for super.

What the hell man. So what. Ideal voltage (AC or DC would help), ideal coil (core or air core would help), we know this will in any way lead to what. The coil has 5H of inductance since it's ideal it cannot have resistance. OK so what. You want to talk about what? There is not even a question mark in your question plus no real question in your question. At least if you said there was a secondary with a resistive or inductive or capacitive load, that would add some more meat on the table. You just put a high inductance coil and count seconds with voltage levels. Look man, your question was just as ambiguous as your wine glass question. That is not my fault. Why don't you just take the cue or is your method a one way street. Do you want to have our input or not.

When I say help, it's not help for us, it's help to turn your question into a real question. Start there and we will see. Yes I can play your EE game any way you want. You think not but that's because I am on another road from now on but it does not mean I cannot play the EE game. I now consider myself a bilingual OUer. I can speak EE and now SC, but you know what, SC is so much more in tune with OU then anything EE can even start to muster because EE is just a convoluted mess full of freebies. Remember the 5 simple questions I asked and no one dared answer. hahahaha You have just been trained to think otherwise because it paid the bills. But I can play the game. The only reason I ask EE questions is to have the answer come from an EEer so it "sounds" official. It's not because I do not have the answer. hahaha

But your attitude, day after day, If you can't answer this, then you are that. Who the hell are you to say such a thing. If I was the moderator I would have deleted you weeks ago and saved everyone one whole pile of junk talk. You accuse @tinman after 6 years for what. Dammit he did more in  6 years of benching then you have since you every started on this forum so what's the problem here. Who should have the say? Then you say I will be just as stupid after another 10 years. What the hell are you saying. What I am working on is levels harder then anything you have ever brought forward to help Ouers. So you think we will arrive at OU by strictly adhering to your EE doctrine. Fine you lead the way. You have one week to provide an OU solution with your EE doctrine. Good luck. Oh but you should not need luck because you have all the answers right. Wake the hell up man. The world is going to shit and we need OU right now and will give it out free or charge and you are worried about what? Wake up man.

You want something to really think about. Look at post 143.

Do not post there because that is not the place. I will open a new thread called "wattsup with AC" when I'm ready but look man, I am not the enemy and you should not be the EE protector. You should be looking for the truth in these questions just like any other sane person should.

Well like usual Brad you are saying stuff that is totally whackadoo and I am sure some of your friends around here are reading it and know that you are saying stuff that is totally whackadoo but so far none of them are saying anything about it.  That is a "sickness" you see on these forums.  If nothing happens then perhaps the usual will happen, a spoon feeding session from a guru.  But why always a spoon feeding session when you are living in the information age, and you can educate yourself if your friends refuse to help you?  For you spoon feeding is clearly not working.  Like I have said many times, you would not survive half a day on a real electronics forum.  You are getting the real deal from me about the easy question and the tough one that I answered, and all that you can do is obstinately refuse to try to do some critical thinking.

Here is the big exercise in critical thinking for you:  For the sake of argument and for your own benefit, assume that I am right and then take it from there.  Come up with an action plan and do something.

There is nothing wackadoo about my answer to your question,as it is the correct answer to your question.

Your question was-->You have an ideal voltage source and an ideal coil of 5 Henrys.  At time t=0 seconds the coil connects to the ideal voltage source. For three seconds the voltage is 4 volts.  Then for the next two seconds the voltage is zero volts. Then for two seconds the voltage is negative three volts, and then for the next six seconds the voltage is 0.5 volts.  Then after that the voltage is zero volts.

The correct answer to this question !is!-at T=0 ,when the voltage connects to the coil,the current rises instantly to an infinite value.

How do we know the current rises instantly?, Because T=L/R,and as R=0,then T also =0-->instant.
How do we know the current rises to an infinite value?,because the ideal coil has no resistance to appose the rise of current,and the voltage applied across the 0 value of resistance is also ideal.

So there you go MH,you asked me to answer your question,and i have--that is my answer.

So,am i right or wrong?

I am sure some of your friends around here are reading it and know that you are saying stuff that is totally whackadoo but so far none of them are saying anything about it.

Perhaps,like your EE friends,they are not interested in getting involved in yet another argument between myself and you MH.
Perhaps the EE guys know that i am correct,but will not say anything,as that would put you in a worse position than you are in now.

If i am wrong,then i would hope that those better versed in EE than myself,would post a comment,and say that i am wrong--along with why i am wrong--as long as it refers directly with your question,and not some random !if we change this,if we change that! changes made to your original question,then this would happen,and that would happen.

Your question can be answered when compressed into a very simple question.
Can an ideal voltage exist across an ideal inductor?.
Your answers say that it can,and my answer says it cannot.

When is an inductor considered !ideal!-->when it has no capacitance,and no resistance,but only inductance.
When is a voltage considered !ideal!-->when it maintains a fixed voltage drop across it's two terminals.

So you are saying MH,that you can have a fixed voltage drop across an inductor that has !no! resistance-->an ideal resistance value of 0 ohms.

Perhaps you can find some one that is willing to stick there neck out,and back you up on this one.

Why have not the EE guy's here,not yet jumped on me,and said that i answered your question wrong?.

The analogy of water and electricity. voltage is the pressure like water pressure ,current is amount of charge ether or amount of water. All interrelating with the size, length, resistance, contours of the pipe work..

Brad:

Perhaps the EE guys are fed up and want to see you sink or swim on your own.  We both know that if Poynt came here and backed me up then you would stop being belligerent and shut up and listen.

Here is a good example of why they might be fed up:

<<< Because T=L/R,and as R=0,then T also =0-->instant.  >>>

Firstly, there is no bloody resistance in the example, so why in hell are you even mentioning a resistance?  Secondly, let's put that issue aside and look at your statement.  You are saying that "Tau is also equal to zero" but Tau = L/R so when R is zero then Tau is equal to infinity, not zero.  What the fuck??

Right now you are completely mixed up and apparently don't know where to start.  You looked up some stuff online and presented some links but you draw incorrect conclusions from the links.  The question is very basic.  It's an important question because if you know how to answer it then you can look at a circuit on paper and get a preliminary sense of how it works.

I think you should try to get a discussion going with your peers but leave out the gurus.  Figure it out among yourselves.  Whatever you do is up to you but I am telling you with 100% certainty that right now you are dead wrong and all of your trash talk about me is bouncing right back at you.
