When you believe that light transferring energy and momentum is the biggest lie told by mainstream science, you'll obviously need a wire to transfer your energy. And when the wire ends, how does the energy go from one wire to the next? Magic, pure magic! |

Magic, pure magic! --- End quote --- Electrical energy will only pass through a gap in circuit if there is enough potential energy (high enough voltage) so that electrons can jump that gap. At 1m air gap you will need almost 3 and a half million volt. You confuse energy storage in a capacitor with energy going through a capacitor. When you connect two wires to the battery so not close circuit just two parallel wires unconnected to echoder each wire on one terminal of the battery the wires will experience an charge imbalance with one wire getting extra electrons from battery and the other donating the same amount on the other terminal. If you disconnect this wires from battery they will keep their charge imbalance and the battery will now have less stored energy than it had before. Keeping the wires after the charge was transferred (a few nanoseconds) will not make any change. Connecting the wires again will also not make any change unless you short the wires for a moment so that excess electrons from one wire are donated to the wire that has the deficit basically discharging the stored energy. Is there any part from the above that you think is untrue ? |

If you write words that disagree with the textbooks, then you are wasting your time because you won't convince anyone else and apparently you don't wish to learn. Either way, you are wasting your time posting. --- End quote --- Show me the textbooks that say "energy doesn't travel inside the wire" as that is exact quote Derek made. --- End quote --- Here ya go. --- Quote ---It is evident that the power flow is through the empty space surrounding the circuit, the conductors of the circuit acting as guiding elements. From the circuit point of view we usually think of the power as flowing through the wires but this is an oversimplification and does not represent the actual situation. --- End quote --- J.D. Kraus, Electromagnetics Chapter 10, P.418 http://xn--webducation-dbb.com/wp-content/uploads/2019/09/McGraw-Hill-electrical-and-electronic-engineering-series-John-D.-Kraus-Keith-R.-Carver-Electromagnetics-McGraw-Hill-1981.pdf Let me guess? You're gonna start railing about how Kraus, THE Kraus, 'doesn't understand capacitors and energy storage'? :-DD :-DD :-DD You really ought to familiarize yourself with the textbooks Derek is using as his source material. Kraus' diagram of the Poynting energy flow on P.417 is very standard in advanced electromagnetics. https://en.wikipedia.org/wiki/John_D._Kraus |

How does the electrical energy get there across the air gap? http://ffden-2.phys.uaf.edu/104_spring2004.web.dir/arts_mcnulty/howmicrowaveovenswork.htm There is plenty of electrical energy crossing gaps but not an electron in sight - except inside the potato. There is a thing called... di... duh...diissssplacement currrrreeennntttt. Electromagnetic radiation? Photons? Ever heard of them? >:D Now, of course you might try to say that microwave radiation doesn't belong in circuit theory... but why not? Maxwell's Equations are perfect descriptors of both phenomena. The consequence is freedom from the confines of wires. It's okay though - Tesla was going wireless before the world had wires. :P |

And when the vacuum ends, how does the energy go from one vacuum to the next? Magic, pure magic! Yes science looks like magic to people without knowledge. It's ok. You can learn if you want to, but you have to stop mocking it first. --- Quote from: HuronKing on May 23, 2022, 08:02:07 am --- --- Quote ---It is evident that the power flow is through the empty space surrounding the circuit, the conductors of the circuit acting as guiding elements.

Sure, it's simpler. b) He didn't justify, in any way, how it does not represent the actual situation. |
