Re: HV Probe Suggestions
NO. WRONG. - A lot of people seem to have this same GCE lately.
The Voltage [aka -STORED- ENERGY] has to be present -first-.
Just before the wrench touches -all- the energy is -stored- in the battery.
After you touch the wrench the energy moves [aka current] through the wrench.
The energy is turned into heat [I2R losses] and makes the wrench hot.
Only AFTER energy moves out does the batteries voltage go down.
[The voltage goes back up when you remove the wrench due to a chemical reaction which for all intents and purposes is the same as charging it with an outside source so that is irrelevant here.]
.
.
The SAME thing happens when you load an actively producing power source.
The voltage doesn't dip until AFTER current flow goes up.
In this case it goes down because the out energy is greater than the in energy so the stored energy [aka instantaneous Voltage at the source] is reduced..
The voltage only returns to what it was if there is a regualtor that causes more energy to in.
.

No you can't.
That argument ignores the Laws of Conservation of Energy.
Energy doesn't just go poof. It gets moved or changes in form.
.
You can have a high current reduce a pre-existing [aka 'open circuit'] high voltage by rapidly moving energy away from where it's stored.
But you cannot achieve that same high current by initially starting with the low voltage as the 'open circuit' voltage at the source.
~
In otherwords:
- High voltage is a prerequisite to high current.
- High current moves a lot of energy from one place to another.
- Moving the stored energy elsewhere causes the voltage to go down.
.
It all happens in a faction of a second which faster than human senses or meters can respond or detect what happens first.
[And that's where the GCE comes from because meters and uninformed humans think it's simultaneous.]
It is NOT simultaneous and it happens in exactly that order EVERY TIME.
.

There is no such thing as "millohms of voltage" and the rest of your thought is either too screwed up or too poorly explained for me to figure out what you mean.
If you have 10,000v on a cap and put 600 ohms across it you will instanateously achieve 16.7 amps through the resistance.
THEN, as the energy is moved out of the cap the voltage goes down.
THEN, the current goes down because the voltage is lower.
~repeat~ for each instant until there is no more energy stored in the cap.
If there's not much stored energy in the cap then all the instants occur in a fraction of a second which is too fast for human senses [or meters] to detect and it 'appears' that voltage went to zero instantaneously.
But it didn't.
