However, equations are not the question, here. Maxwell debunked the hydraulic analogy for the flow of energy based on experimental data. He noticed that a stretch of wire through which a current was flowing would tend to show a spike of voltage if interrupted at the point of the interruption, just like a pipe experiences sudden pressure at the point where a valve has interrupted the flow. However what hinted him that the energy didn't flow like a fluid in a pipe is that if you coil up the wire the voltage increases, while with a coiled up pipe you do not have this effect. Also, if you put a piece of iron inside the wire coil, the voltage will increase even more, but not the pressure for the pipe coil. Electricity flowing in wires affect other wires nearby not connected to each other either by attracting or repelling them if they too are conducting current, or inducing voltages if the currents vary. Derek repeated the experiment Maxwell observed, only that, instead of opening the switch, he closed it. And he observed that, unlike a pipe, where the energy would never arrive at 1m/c, the electric energy does, and that the hydraulic analogy is what it is, a (should I say poor) analogy, not a description of How Electricity Actually Works. So the experimental data debunks whatever theory you may have to sustain your misconception. --- End quote --- As any analogy there will be limitations but I was not mentioning the hydraulic model in my demonstration. https://www.eevblog.com/forum/chat/veritasium-how-electricity-actually-works/msg4156462/#msg4156462 Derek clearly has no understanding of what energy is and is not just based on this two videos related to "how electricity actually works". Do you agree with this simple statement: Energy flows in or out of a capacitor and not trough a capacitor. I say and is easy to demonstrate that energy flows in and out of a capacitor while Derek that has no clue what energy is basically saying that energy flows trough a capacitor. |

Why not both? Stick a 10mF capacitor in series with an AC load and tell me it doesn't transmit energy. :) Tim |

You will have a lot of heat loss in the conductors due to repeatably charging and discharging that capacitor. No energy will get across the dielectric. That is why there is no current with DC after the capacitor is charged and gets to same voltage as your source and if you disconnect the source and short the capacitor you will get all that energy you put in back as heat. Edit: And if you attempt to do this test make sure to use a non polarized capacitor (likely much smaller value than 10mF as you do not need that). Use a resistor to limit the current. |

Whelp... time for another experiment I guess. Ed: You're not just thinking parallel (shunt), right? You know what I mean by "series"? Tim |
