And if fully developed my theory will give numbers for transients. Old electricity can't even give good numbers for steady state, eg the half voltage double time for discharge of a capacitor (which my electons explain in the simplest possible way). --- End quote --- There is no "voltage double time" for the discharge of a capacitor. Buy a capacitor, discharge it through a resistor and measure the voltage across the capacitor as a function of time. You will see that the voltage decreases exponentially with time. It is only when the physical dimensions of the capacitor is in the same order of magnitude as the wavelength, i.e. at high frequencies that we have to start worrying about the electrodynamics of the capacitor. In this case "old electricity" explains everything perfectly. Similar to what I showed you with the transmission line. There is no scientific conspiracy theory! Let us know when you have equations. Until then, I will no longer read your posts. My wife cannot handle the laughter any more. |

I can see that on one side of the switch we have +4V & on the other side of the switch we have -4V. But when the switch is closed we immediately have 8V. Looking simply at drifting electrons producing a wave, there will be an 8V wave going right (to the terminating resistor), this will be a depletion wave, ie that wire (which includes the outer sheath of the coax) is electron rich, & the conduction electrons will begin to spread out. And, there will be an 8V wave going left (along the core wire of the 18m long coax), this will be an enrichment wave, ie the core wire is electron poor, & the electrons will begin flow into it & begin to bunch up. If the core wire was neutral, ie with 00V, then in that case there would be a 4V wave going right & a 4V wave going left. But it aint neutral, it has +4V. (2) Nextly i could explain why it is an impossibility for an electron wave to reflect at a dead end of a wire. Or, putting it another way, why such a reflexion would not add to the gradual addition of electrons into that wire, ie it would not add to the gradual bunching up of electrons in that wire. But not today, i might explain later. (3) Here is my main objection. U chose the propagation speed of light, but in a part of your explanation u invoke an infinite speed of light for one of your 4V waves. U have this wave starting to wave at t=0 s, at the end of the coax, which is 18m from the switch. (4) I noticed a few things, as an interesting aside, not necessarily a criticism of your explanation. And u might address some of these things in your detailed explanation later. I noticed that u did not mention drifting electrons (& what parts they played), surface charge (ie surface electrons)(& surface charge distribution), Poynting, & whether electrical energy is in or on or near the wires. (5) Re a capacitor not being a transmission line. Perhaps so, in a way. But a transmission line is a capacitor. Perhaps it depends on whether ends are open or shorted. Perhaps it depends on the kind of source producing the electricity (ie the charge)(eg a lead acid battery). Anyhow i don’t see how arguing about that stuff would help us today. --- End quote --- I will attempt to address your misconceptions in the note I am writing. In the meantime, let me set a challenge: Let's change the termination resistor in Catt's paper from 75Ohm to 47Ohm. How, according to "new electricity", will the measured pulses look if we do that? --- End quote --- We are still waiting for your explanation of the infinite speed of your half wave. |
| SandyCox:
There is no change in the value of v+ at z=-18m just after t=0. The value of v+ at z=-18m is constant. I only drew it in this way so that it is easier for the human mind to comprehend. Just think of it as a solid blue line. There is no infinite speed. Furthermore, on their own v- and v+ have you physical meaning. They only have physical meaning if we add or subtract them. |

What happens when you have less than 1m distance between the wires? 0.1m / c? Nothing can travel faster than light? |
