MH's ideal coil and voltage question

[tinman]

If there is no resistor in the schematic then you do not discuss an imaginary zero-ohm resistor that you want to force into the schematic.  It's a non-starter.

I told you Brad to try to work it out with your peers or work it out by yourself.  I am not going to supply you with the correct answer.  If I did that you would balk anyway and fight over it for 100 postings.  I am not doing that.

"You are wrong."
"Okay, now give me the right answer."

It's not not going to work like that.

."

You clearly have no understanding at all about how an inductor actually works.  That is the essence of the question.  Why don't you start there?

So you are not here to debate or discuss your question,but only to leave it to me to do all the work.
So much for you insisting on debating things

You should say, "Okay, I will discuss it with my peers and go do more research and learn more and improve my skills so that I can answer the question successfully by myself

My skills are fine thank you MH.
My answer to your question above is correct,and as you have provided no answer other than to say mine is incorrect,we can safely say your answer is incorrect,as i believe mine is correct,and you disagree with my answer.

As you have not provided any proof that my answer is incorrect,nor have you attempted to answer a couple of simple questions,we can assume that you cannot answer them,nor can you provide evidence that my answer is incorrect.

So as you do not wish to be a part of this debate,or help others find the answer to your question,i will post some answers for you.

Q1-can a voltage exist across an ideal inductor that has a DC current flowing through it.
Your answer MH (if you know your stuff)will be no,a voltage cannot exist across an ideal inductor that has a DC current flowing through it.
Have you ticked this box in the pole question?--seems not.

So now that you agree that a voltage cannot exist across an ideal inductor that has a DC current flowing through it,how can you have a voltage of 4 volts existing across an ideal inductor for 3 second's--an inductor that has no resistance?.

<<< no,a voltage cannot exist across an ideal inductor that has a DC current flowing through it. >>>

And that's probably the only thing that you have stated about this subject so far that is correct.

I will repeat to you:  I already answered a variation on the question that is actually more difficult to answer.  I gave a complete and full answer.  It's up to you and your peers to try to answer the simpler question if you want to.

I am just waiting and hoping for a successful conclusion.  I will repeat:  You clearly have no understanding at all about how an inductor actually works.  That is the essence of the question.  Why don't you start there?

If you don't get a guru parachuting in to help you and you and your peers are unable to answer a question about one of the simplest circuits possible, so be it.

These are the only two things I am interested in hopefully seeing a successful resolution to:

1.  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.
2.  Brad admits that he is wrong when he stated that my response to the harder question is wrong.

I would suggest at this point in time,you review your question,and not treat your inductor as a normal inductor that !dose! have a series/parallel resistance.
You clearly defined the inductor and voltage as being !ideal!.
You said your question was not a trick question,so i think you need to go and calculate the L/R time constant for your ideal inductor--some how
Once you have that L/R time constant value,we then only need multiply that by 5 to get a close approximation  for the time it takes that 5 henry ideal inductor to reach it's steady state current value after T=0-->the ideal voltage is applied across the ideal inductor.

All i ask is that you calculate the L/R time constant of your 5 henry ideal inductor.


Brad.
How are you to work out the L/R time constant when there is no R

[tinman]

MH,

does the question ask for when T=0

It does not start when T>0 the question is for when T=0

T=0 is the start of the cycle --> the instant the ideal voltage is placed across the ideal inductor

You are lost Brad and you should take my advice and start from scratch.  And like usual you are completely baffling because some big clues were presented to you and they passed right through you like you weren't even there.  I am giving you a 10% chance to get it right.
