i'd guess, given the conditions are that it's DC, that the greater the distance the greater the resistance, so a circle version would not light up, without incredible voltage that would probably fuse regular house wires it's just that most people don't understand that electrical current is conveyed by a magnetic field and magnetic fields have zero mass so the time of travel is about hysteresis, which for copper wires is very low as it isn't ferromagnetic... but it's high enough that it seems like the same or near abouts the same as light speed. an experiment using an iron conductor versus copper would confirm this this is an old debate, also, and the reason why tesla was right and edison was wrong about DC current the resistance is too high for safe DC voltages, and foot thick wires are just not very practical in terms of cost of production there is a lot of misconceptions about the nature of electricity everything is electromagnetic, electricity really is just literally the phenomena of kinetic energy transferred over magnetic fields this is why this idea you can't create an impulse engine purely via electricity is wrong, electrons are matter, you jsut have to get them in a quantum configuration that turns the velocity into mass long enough to do the newton thing also i'm not sure sasha is a woman... it's actually a slavic pet name version of alex

yes, the kinetic energy the *changing* magnetic field it's difficult to even say which one is which, is kinetic energy a changing magnetic field or is a changing magnetic field kinetic energy? this "gravitational potential energy" which is the spook in the middle of this equation, is the energy that is carried by an electromagnetic field, that literally enables you to spin a wheel on one side, and a loop of wire with a coil on each end and you can transfer that kinetic energy directly as spin (given good geometric arrangement) to another, sans the resistance loss of the resistance of the loop of conductor between what's interesting, to me, is that though the change of the polarity has a kind of inertia (which is proportional to resistance) it does not have a time of travel, only a limitation based on the medium the current flows through, which gives you resistance resistance creates heat in the conductor but heat can also alter the flow of kinetic energy via newton's equal and opposite this is why it's an absolute travesty that we still don't have public access to tesla's papers because there is good reason to believe he mostly figured out how to directly take that field potential out of the earth and directly generate current and this shouldn't be amazing because in fact, earthquakes mostly happen via piezoelectric action caused by electrons thrown at us by the sun and caught in the poles of the earth's magnetic field with the way that this magnetic field is weakening at this time, as a rotating field oscillation that passes every ~6000 years through 90 degrees from the centre of the galaxy, if humans could just figure out how to use the endless energy that is currently on in the process of going massively hockeystick to protect ourselves from the earthquakes, storms and volcanoes that this weak magnetic field is also going to induce i didn't mean to interrupt the discussion, per se, just that my models of energy and motion and matter have been greatly impacted by recent understanding about how magnetism and electrons and protons flow around the solar system and galaxy and how it affects the weather, especially but that's massive amounts of energy, i mean massive, i mean retarded amounts of energy, and in normal times it's enough to run all the machines, but in these times it could launch us to deep space

yes there is many, if you watch the Suspicious Observers channel every other day he's announcing new geophysics papers he's found that have discovered influencing relations between solar energy phenomena and earthquakes much of the rock in the crust of the earth contains piezoelectric reactive quartz crystals that deform when you put current through them of sufficient voltage, and the rest of the material is mildly conductive materials, like, the iron/magnesium/aluminum of basaltic rocks, and quartz is not just piezo but amorphous silica crystals in general can hold surface charges, like the way it is used to make ceramic capacitors, and how they exert their adsorbent effects as used in chromatography and other things like water purifiers catching ions and cations
