What's the significance of VHS tapes?
- chromatin 4y agoConductive
- burritas 4y agoSeems like the tape would get burnt up before too much damage was done though.
- dismalpedigree 4y agoYes, but across sufficiently high voltage lines the initial arc would create a plasma channel which would act like a thick wire for the short to continue
- nightshift1 4y agoI guess it's probably not enough to sustain a long time and there are probably protections in place to prevent that. Here is a short video showing someone doing almost exactly this: https://m.youtube.com/watch?v=X_2lZqyCmls https://m.youtube.com/watch?v=X_2lZqyCmls
- dismalpedigree 4y agoPretty confident that video is fake. The concept holds though. This video seems more realistic. https://youtu.be/2NKOlLDNknc https://youtu.be/2NKOlLDNknc Point being the initial path creates a plasma channel that then bridges the gap and lets current flow.
- maxerickson 4y agoSo I would expect an outcome like 3 or 2 in this video (where something bridges the lines, established the arc, and then it goes away): https://www.youtube.com/watch?v=gOT8jx4jEzM https://www.youtube.com/watch?v=gOT8jx4jEzM Is the arc dissipating because an automatic system is killing power to the lines? Is there going to be damage elsewhere in the system from events like 3 and 2 in the video there?
- monocasa 4y agoNo it works pretty well. You're essentially making a thyratron. https://en.wikipedia.org/wiki/Thyratron https://en.wikipedia.org/wiki/Thyratron
- anigbrowl 4y agoLightweight but relatively strong conductive ribbon
- BLKNSLVR 4y agoSubtle reminder that I have to return some videotapes.
