Well the idea is that the current capability is so low that any resistance will lower the voltage to where some current will flow. i.e. the output impedance is very high. Most modern components will then show the voltage at which they are starting to break down. Having said that, it is true that old capacitors may break down and be damaged before the voltage is reduced. I have seen this on 60 year old paper capacitors. So this device should be used with caution.
Great video.. with a lot of exampled usecases..
Exactly what I need to test some suspicious MOSFETs. I am in the process of making an electronic adjustable load.
can you share the schematic ?
@gaberboraey5477 Google ElectroNoobs, it is on his website.
I would overvolt capacitors, as they are not rated for such abuse. Best to apply rated voltage and observe leakage current.
