[QUOTE="Water Bear, post: 8867812, member: 673826"] I'm late to this discussion but the water analogy typically used to explain current (flows from high potential to low, potential differences can be used to do work, etc) goes only so far. In particular Bernoulli's principal doesn't really make sense for electrical current. Current is "compressible" - that's what a capacitor is, basically. Bernoulli basically says that if you increase resistance to flow, flow goes up (to maintain flux - it's basically an application of conservation of momentum). As we know, the opposite happens to electrical current. The water analogy makes sense to a degree, but it can go too far. Another big difference is that electrical systems do work with fields, and changing electric fields create magnetic fields (that's how a voice coil works). With water the work is done by physical momentum and there's no "complimentary field" for something like a velocity field. Electrons don't actually flow through a wire like you might imagine they do. In summary: **** be crazy, yo. [/QUOTE]
