    Putting aside my opinion about the appropriateness of your response, if it was in response to anything that I wrote that implied that you shared crashsite's sentiments, then I have not made that determination.

    The formulas that I am - to use your word, throwing out, are ones that relate resistance to distance. I am not sure what these forumlas define because I don't know how L is described. I have not given up on Ohm's law. I am only looking for a way to describe resistance as a function of distance - whether this involves combining Ohm's law with another equation or not. Notwithstanding your statement, I think that this involves electronics.

    It would be helpful if someone would tell me if L in R = pL/A = pL/(Wt) - at Sheet resistance - Wikipedia, the free encyclopedia, means length of the sheet, the length between arbitrarily located point electrical contacts on the sheet, and/or the length between a different type of electrical connection resulting in a uniform current through a line defining a side of the sheet - and perhaps a uniform current through the opposite side as well.

    It's the formula to estimate the resistance form one end of a sheet to the other.

    Read the Wikipedia artical, it should be fairly obvious.

    I will not try to help you any more unless you answer the problems I set you in my previous post.

    It is obvious to me that L has something to do with the length of the sheet. It is not obvious to me if the formula is independent of the location of electrical contacts; if L means the distance between electrical contacts; if L does mean the distance between electrical contacts - if the electrical contacts as implied by the formula have to be point contacts, or if the electrical contacts have to be such that there is one or two uniform currents through lines defining opposite sides of the sheet.

    I'm trying to figure out if a formula - Rs = (V/I) * CF - at Sheet Resistance might apply. Does anyone know another name for CF that I can use in a search?

    Put up or...keep being a simp????

    You have to learn to walk before you can learn to run. I would suggest that we withhold all technical assistance from this guy until he shows that he has at least taken the effort to learn and be able to apply, Ohm's Law.

    I love the idea of putting the ball in his court and watching him squirm as he conives ways to try to continue groveling for attention without actually showing any cognizance.

    It surely shouldn't be too difficult for a guy who is asking for detailed technical information on advanced levels to be able to show compentency in something taught in the first week on any high school level electronics class.

    Okay, okay...I thought I could do it and, bleieve me I wrestled with my demons (and lost) so...

    Perhaps an appropriate search for CF for you might be, "c**t face"?

    I think hes doing rather well being you keep giving him the attention! Direct attention or not, he is still hanging in there thanks to you! :p

    :D

    I am almost half tempted to give jasonbe positive rep points just for playing you guys so very well! :eek::D

    As inept as he may look at electronics and electrical theory he obviously knows how to play this game and he is playing it very very well! :eek:

    Crashsite in the post that I am responding to compares learning Ohm's law,
    V = IR, with learning how to walk. I don't want to write anything that would discourage people from participating in this site because of math. However - while the math for this formula might not seem to be the most advanced, the molecular activity associated with it seems to me as though it could be studied in depth. How much crashsite believes that a person should know about molecular activity associated with this formula before participating in this site, I do not know. Perhaps there are simplified ways of describing the basics of molecular activity that relate to Ohm's law and maybe even describe it partially or in full. I can't say that I understand the basics at this time - and I don't know if they are known by anyone at this time.

    The formula can be rewritten as R = V/I. The term that I meant to express interest in is a constant multplied by V/I. Putting the chemical significance of the term aside - which might be considered acceptable to do if crashsite is accurate in saying that Ohm's law might be taught in the first week of a high school course, mathematically, V/I does not seem too much more difficult to calculate than a constant multiplied by V/I. In this case, the constant is CF - which I think is the resistance correction factor, and the overall equation is (V/I)*CF.

    I would be interested in knowing for what reason crashsite thinks that it is acceptable to learn R = V/I and not V/I multiplied by CF. I would like to know if anything besides perjorative language supports crashsite in this instance.

    This may be risky, but I am tempted to ask you, as long as you are playing along - why is it likely that the sites that I have found describe the resistance correction factor - if that is in fact what CF stands for, as a function of only temperature and not probe spacing.

    I try not to pass up educational opportunities. I don't feel like I have to either agree with or respect someone to be able to glean some insight from them.

    I also don't mind doing a little "baiting" now and then when I feel that someone deserves it...occasionally, sometimes even when they don't. After all, I did succeed in making one of the guards laugh at Buckingham Palace but, to be fair, it was at one of the gates on the back side and I figured it was good practice for him if he ever expected to make it out front. But, I did promise him that I wouldn't tell the Queen and...unless she reads this forum...I still haven't.

    But, don't think I didn't notice that Mr. be's Ohm's Law dissertation is as rambling and as full of as much nonsense as he figures he can load it up with and still "satisfy" the requirement. But, as the Queen herself might say, "We are not amused".

    I always wondered who the other or others were that made her refer to stuff with a we?
    Does she have an invisible friend?:confused:

    dont know if you were being sarcastic, but the real reason is just as goofy. Its that she supposedly speaks for the whole country "we" = "all of england" haha

    Can I patent cold fusion, teleportation, a cure for cancer and light speed travel? I haven't created them but I'd like to.

    Couldn't find it in a US patent search engine.

    I can see what you're asking but you need to learn the basic first.

    For the final time, answer the questions I set you or I will not help you.

    I'd have to reresearch patents to give an acceptable reply to your question. When I wrote that, I think that I was thinking that the word "patent pending" did not require a provisional or non-provisional application. I never submitted one. I don't know how much recourse I would have if someone decided to profit from the idea - mainly because I never conducted a thorough patent search. It might be to my advantage if someone else - who was able to mass produce the product more than I could, profited from the idea - because my interests is in the popularity of the idea and data as well as a profit. However, this is not intended to release any rights that I may have to the device. I'd like for such a device to be used for educational purposes as well business. If I remember correctly, in the United States, intellectual property is granted to the inventor. This, I think, is different from Europe - where the first to file - not invent, is given credit. Perhaps this has something to do with the population of Europe. I don't know about the policy of other areas.

    You should take the phrase "patent pending" off your description on your site. Are you in Europe, North America or elsewhere?

    PS patents are pretty much useless for sub $12,000,000 dollar ideas. And a DIY one is worthless, you need a patent lawyer and can cost from $10K to $100K

    As for the requirement that crashsite mentioned, how much does crashsite expect a person to show that they know about how temperature, lattice structure, collisions, boundaries, strain, or anything else - as they specifically effect molecular activity, is related to Ohms law, before they can participate?

    I may have made mistakes that involve thinking that the material that I am looking for is ohmic. It is difficult for me to conceptualize how current and voltage might not be independent of each other in a formula describing the resistance of a material. However, I do not think that this would disqualify me from participating - or being given information related to if CF means resistance correction factor, chordal resistance, or something else.
