In simple terms, for two oppositely charged parallel plates, why is the electric field "CONSTANT ANYWHERE" between the two parallel plates? It still doesn't make sense to me up to now!
ITS NOT.... but if you ever try and stick a meter into it to test it... you would find the same field across the board.... it is beyond our technology to test for whether or not the field of force is dispursed or whether it is composed of discrete one dimensional lines of tension or flux. no one can answer the question... and you willl get alot of answers telling you that yes it is.... and they are very sure of it.. but it is belief. if you test for it... you may get fooled... alass.... a stroke of genius... at this very moment, i came up with a way to test it. but it is beyond my means to do so at this time.... or is it??? hummmm... fascinating stuff,, thankyou. -MT
MT, please stop posting your nonsense to confuse people taking physics classes. Kingwinner, do you understand Gauss' law? The easiest explanation uses Gauss' law and symmetry: Consider a single infinite plane of charge. By symmetry the electric field is everywhere normal to the plane of charge. Now, consider a cylindrical Gaussian surface where the side of the cylinder is perpendicular to the plane of charge and the ends are parallel to the plane of charge and equally distant from the plane. The electric field is parallel to the side so the electric flux through the side is zero and all flux goes through the ends. By symmetry half of the flux goes through each end. As you symmetrically increase the distance of the ends, the same amount of charge is enclosed and therefore the same amount of flux goes through each end and therefore the electric field is constant. -Dale
This came up in another thread: [THREAD]56025[/THREAD] I posted a qualitative explanation that doesn't use Gauss' law there (though if you're not familiar with Gauss' law you're encouraged to look it up).
Test/prove what? There's no ambiguity in the predictions of Coulomb's and Gauss' laws, and they're backed up by well over a century of experimental evidence. Do you have a good reason for doubting the validity of these theories?
THE main question here... is whether any electric field... is made up of discrete parts.... or... is instead a smooth spread medium field... without any discrete nature whatsoever.... this is a huge debate, of which you maynot be aware of... so many love to state plainly that the field is uniform through out... but they fail to recognise that it is due to the even distribution of the lines of force in question existing between two bodies... this field being made from not one electron proton pair but billions apon billions... and it is the combined field of all these charges which results in the evenly dispursed field we see in our testing. some argue that these so called one dimensional lines of force do not exist, and that some how the field is somekind of dispursed something something.... when pressed for clear explinations as to why that sort of logic makes any better sense than the logic suggested by lines of force... they draw a blank, and make meaningless arguements... which will NOW happen. -MT
No, MT. The main question here is "for two oppositely charged parallel plates, why is the electric field "CONSTANT ANYWHERE" between the two parallel plates?". Kingwinner is a student looking for a basic understanding of physics fundamentals, not a crackpot looking for a non-existent argument. Then it isn't such a huge debate. -Dale
yes... 2 plates.... even field.... field of what???? lines of force?? from what?? protons.... to where...??? removed electrons.... forming what? a collective field of lines of force.... a force which naturally evenly distributes, due to some here to date unexplained repulsion between said lines of force. many people will try and confuse you with lots of logic, mr kingwinner,.... but remember... truth, and what we use to 'work with something' can be two different things... it maybe true that the field is made up of discrete lines of force... but since they all manifest and function as one body... one same field of force, in parralel.. it doesnt matter and we can look at it as if it is some evenly distributed field of force... and for all intensive purposes it maybe... but in reality.. truth, ,maybe that this field is composed of specific and discrete parts which themselves have unique properties... and i am talking about lines of force. lines of force are fundamental to all of modern science, and yet for some reason alot of people... will try and tell you that they dont exist. -MT -MT
Lines of force are an obsolete concept, abandoned long ago, except as an expediant to visualize and graghically represent fields of force.
How can you confuse someone with clearly formulated logic? Please Register or Log in to view the hidden image! Science deals only with measurable phenomena. Coming up with an explanation as to why electromagnetism works the way it does without adding anything to the predictions it makes, or deciding which of a number of experimentally indistinguishable theories to call the "truth" is the realm of metaphysics and pseudoscience. There's no point in providing an invisible, undetectable explanation for any theory. For all anyone knows, it could be invisible magic pixies that are responsible for pushing electrons away from each other and toward protons. Or it could be the universe's collective all-pervading "energy consciousness." Or it could be Santa Claus. There's simply no way to tell if any one of these is true. They're one way of graphically representing electric fields. They have their uses and drawbacks.
ok then... fundamental question... this fundamental electric field... eminating from a proton... does all the field exist on one side of the proton towards the electron??, or does it instead spread out evenly in all directions from a single proton??? REMEMBER.. its a force... it must have magnitude and direction. did i say direction??? yes i did.. and that would mean what?? tangeble fields of force, eminating like vectors... in directions... not spread out as AN intangeble field of something yet explained by any of you. -MT -MT
