Joule Thief 101

Brad:

I am sorry but I am going to be nasty here because you deserve it:

<<< I dont know what is going on with you MH,but you need to make up your mind here.
Can a voltage exist across an ideal inductor that has a DC current flowing through it or not?--it's a very simple question,and you can have two answers as you have above. >>>

Just because the current is flowing in one direction you are calling that "DC current?"  This ridiculous nonsense takes its root from my answering the more difficult question and you haven't mastered the concept of what "DC" means relative to talking about coils?





Inductors are all about current changing with respect to time and you pull off this silly stunt because you don't know?



MileHigh

That is not DC current you loonie that is current that is changing in time.

Now we get to see MH redefine DC current.

DC current is a unidirectional current flow MH.

https://en.wikipedia.org/wiki/Direct_current
Direct current (DC) is the unidirectional flow of electric charge. Direct current is produced by sources such as batteries, power supplies, thermocouples, solar cells, or dynamos. Direct current may flow in a conductor such as a wire, but can also flow through semiconductors, insulators, or even through a vacuum as in electron or ion beams. The electric current flows in a constant direction, distinguishing it from alternating current (AC). A term formerly used for this type of current was galvanic current.[1]

All of this stupid nonsensical idiocy because poor Brad can't make a distinction between constant DC current that does not change with respect to time and current that is flowing in the same direction that does change with respect to time?

Show me the post where you stated constant current MH--you did not.
You clearly stated DC(direct current flow),and no where is direct current describe as constant current flow --you doofuss.

[/b]You are in the corner with a dunce cap on right now.  People reading are aghast.

Look in the mirror MH--Mr dont know what a DC current flow is.

It's not me that has been smoking anything.  Who the hell knows what you have been up to though.  You just fell flat on your face and right now your face looks like a pancake.

I am so aghast, you never stood a chance of answering either question, ever.  You have been bluffing your whole way through this discussion and you just don't know what you are talking about, at all.

If you mean constant DC MH,and NOT just DC,you should learn to use correct terms,and understandings.
Did you not read the pole question on the other thread, where i clearly state constant DC current flow,while you just state DC current flow.
Who dosnt know the difference MH ?--yes,you.

No Brad, you look in the mirror.  What are you even doing here?  Six years of playing with coils and all that you can do is quote a Wiki entry for DC current.  Because you cannot understand what "DC current" means relative to a discussion about coils, it's clearly showing how truly limited your understanding is.

I was hoping that you would get up the learning curve and be able to answer the question that was posed to others, but clearly there is not a hope in hell.  The gurus won't say anything, but I can assure you they are just as shocked as me.  Or perhaps they aren't shocked at all.

MH

Now tell everyone here how you can have a coil with an inductance value of 5 Henry's ,and a resistance value of 0.
When dose induction end in an inductor ?

No Matter how you try and change things around MH,you clearly quoted DC current,and then you admitted that you meant a constant DC current.
Perhaps be a little more accurate in future.
Its much like giving your address as America,rather than your actual street address--no one is ever going to find you.

So now,how did you define your inductance value with an inductor that has no resistance?
The magnetic field will continue to rise as long as the current continues to rise,and having an ideal voltage source feeding this ideal inductor,the current rise will be infinite,and so will the magnetic field. Induction will never stop. Of course in the real world,we also have resistance ,which limits the flow of current,and so limits the increase of the magnetic field to a set amount.
