--- Quote from: TimFox on May 11, 2022, 03:28:27 am ---Two words: quantum mechanics. --- End quote --- So, free photons, emitted by atoms of gas excited by electricity in a laser, act like light etc. And free photons emitted by a very hot glowing wire act like light etc. And, free photons emitted by electricity in or on a wire act like charge and/or like magnets. So, free photons can have say 3 states (light charge magnetism). And QM explains. Question. Why cant free photons have these 3 states at the same time, ie a mixture? Or light & charge at the same time. Or light & magnetism at the same time. Or charge & magnetism at the same time. Thats a total of 7 combinations. Dont tell me, let me guess, the probability of some of these is zero all of the time. |

While the power is still on I remove them, and put them on the bench. They still have charge in them. How can you tell which one was connected to 10V, and which was connected to 0V |

Here even more proof energy travels through wire's and not outside the wire in Derek's example. No that there is any evidence to the contrary but maybe one of them will make you understand this is the reality in this universe. Same LTspice transmission line simulation was used but I have used two examples. First one is with Switched turned ON and staying ON and the second with switched turned ON for just 30ns so it was switched off before electrons got to the lamp/resistor. The graphs show power leaving the source and the power on the resistor/lamp. The resistor is 1KOhm and the transmission line has 20Ohm resistance so there are some losses as energy travels through the wire. This is for switch staying ON. The energy is the area under the power graph and over the 400ns 155.05nJ where delivered by the source while at the lamp/resistor 142.1nJ in the same period This is for the switch being turned OFF (open circuit) after 30ns. In this case just 9.16nJ left the source and 7.68nJ where delivered to the lamp/resistor most of witch after the switch was OFF so open circuit. I think at least two things are very clear from this graphs. There is energy storage involved and energy travel through wire with the missing energy being dissipated as heat on the transmission wire. |

:-DD So you're telling me wires are made of shittons of inductors and capacitors, through which the power flows, and that those inductors and capacitors -- you know, the in-circuit manifestations of fields in space -- are somehow hidden away, packed up inside a tiny hunk of metal? Tim |

Do you see wires connected between the sun and the earth? |
