Say I have a xenon tube tucked up in an inaccessible place where I cannot see it or safely remove it. Does anyone know if xenon tubes like the kind found in camera flashes display a polarity dependent nonlinear characteristic that can be seen for example on an oscilloscope? thanks |

A "polarity dependent nonlinear characteristic"? The short answer is "no". The flash tube will be powered by a DC, polarized capacitor. What are you trying to do? Have a look at https://en.wikipedia.org/wiki/Flashtube |

Afaik the differences on electrodes are to do with rates of erosion over time, so seems unlikely you could measure it remotely. Worst case it just doesn't last as long |

Sorry I should have made clear that the idea is to determine the polarity of said tube electrically when visual identification is not possible. |

Sorry so far no one knows of a way to do it. I think it may trigger at a lower voltage when given the correct polarity, but I could be wrong. |
