Are "static" and "current" really two separate kinds of electricity? I say no. There is only one type of electrical energy. We usually call it Electromagnetism. It's true that electromagnetism has a wide variety of behaviors. Its behavior depends on the strengths of the electric field and magnetic field involved. Electric field corresponds to voltage, and magnetic field corresponds to current. The "map" below is intended to show us that "static electricity" and "current electricity" are really just two fields of science. But electromagnetism itself is a seamless whole, and the boundaries between its various parts exist only in our minds.
In view of the "electricity map", here is how we usually divide up
STATIC ELECTRICITY:Refer to the above map, and note that the left-hand side contains the things involving "current", while the right-hand side has the "static." Things aren't perfect, e.g. where do we put the lightning and the high voltage power lines? These are both electrostatic phenomena and electrodynamic phenomena at the same time.
I believe that talk of "two kinds of electricty" called Current and Static
is profoundly misleading. It hides the true nature of electric charge.
It's like saying that there are two kinds of water, pressurized water and
flowing water. Yet water is water, and water doesn't magically turn into
a special kind of substance called "Current Water" whenever it starts
flowing! There is no such thing as "current water," and there is no such
thing as "current electricity." If something is flowing inside of wires...
just say it that way. Don't pretend that a form of energy called "current
If fur rubbed upon rubber causes a high voltage at nearly zero current,
why not simply say so, instead of discussing a nonexisent "kind" of
electricty called "Static?" In truth, "static" is a separation of
negatives from positives, and if the separated charges should move along,
that is (ahem!) ...A *FLOW* OF STATIC ELECTRICITY. 'Static' means
so what the heck is a static flow? Something is seriously wrong with how
we explain electricity. The cure is simple. Cross out the words "static
electricity" everwhere. This forces us to seek out better words to
