I always wondered how does current know not to pass thru open wires. It doesn't, it learns by probing, not once but 8 times. very interesting video. https://youtu.be/2AXv49dDQJw?si=DEhenh21eBY9XZKs |

Trying to understand the implications of this and how it relates to audio. His set up to measure this is nowhere set in reality, and are these effects even present in an audio system. The fact that electricity travels down an open circuit and bounces back makes no since to me. Also what has been popular for a while now is the grounding enhancements that cost a fortune and have you connect components grounds to a box that goes nowhere and supposed to reduce noise and have better focus if one is to believe the hype. |

Haven't seen this level of detailed explanation anywhere. Since the circuit settles down in nanoseconds after startup, there should not be any effect on audio in run-time. The most interesting part of the experiment was, how he used an oscilloscope's frequency to measure how the current flow in a circuit. Very smart setup.

That explains why we get shock when we touch open wires.

May be experts like David Berning can explain the phenomenon. |

We get a shock from an open circuit because when we get the shock current is flowing, it is not open any longer. He is seeing reflections in the video, it's not a newly discovered phenomenon. |

A wire that ends is only an open circuit at DC. For any f>0, it’s an antenna, and current flows in antennas just fine… Roscoe |
