Tossing a charged Capacitor in the Bathtub
We
grabbed another dead man stick and still got quite a bang out the cap
since it didn't completely discharge before blowing up the other dead
man stick.
Effect of dielectric absorption, possibly? You short it briefly, it
discharges, but then a small portion of the original charge level appears
to come back moments later...

I am familiar with that phenomenon, although in this situation, I'm
pretty sure it was the result of a partial discharge before the
grounding rod exploded. Obviously I can't proof it, that's just my
guess, based on prior experience with these large caps.
As part of our bi-weekly transmitter maintenance, we would ground the
caps prior to removing the bus bars to get them out of the stand-by
transmitter. Before they were even lifted out of the transmitter, we
always put a shorting cable on them to stop them from charging back up
due to both dielectric absorption and the strength of the signal from
the on-air transmitter.
On the rare occasions that we forgot to do this (newbies!) or noticed
a bad ground connection, we would use a dead man stick to short them
before grabbing them. Even after a few hours, the discharge was
minimal and we might get a little bit of a pop. In the case of the
training demo, which was done in a rather neutral environment (the
mess hall, a 1/4 mile from the transmitter building and tower) the
resulting discharge was quire substantial, much higher than anything
we'd seen in "real life".

That's what I've been saying. Well, I said that if you throw a radio
or heater in the bathtub, the current will go through the drity soapy
water sononer than it will go thourhg the bathers body. What is
dangerous is catching the radio when your hand is out of the tub and
the only way to ground is through you.

If you caught the radio before it hit the water, nothing would likely
happen, since it's all plastic. Unless it's one of those real old tube
sets with a metal cabinet and hot chassis.
Now this brings up another question. If the tub is plastic or
fiberglass, water supply is pex or pvc and drain pipes are pvc, the tub
is not grounded. I always wondered what would happen, since the person
inside is not really grounded. (I mean is an AC plugged in device hits

I don't know what will happen when you toss it in the water, but I
know what will happen when a dead man stick is used to short the
terminals of a large cap charged up to 7 or 8 KV DC.
A dead man stick is a device with a wooden handle with a hooked rod
threaded into the handle and a braided strap with a clip on the end.
It was used to both ground towers and other electrical equipment or to
pull an energized human from said equipment.
At a minimum, shoting out the cap will cause a bang and a spark that
is sure to strike fear into the hearts of most mortal men. In some
cases, it will blow 4 inches of threaded rod out of the hardwood
handle.
We used to do it quite often when I was in the Coast Guard as training/
warning exercise.
We had large oil filled caps (5F) that ran at 15 - 20 KV DC in the
LORAN transmitter buildings. We didn't want non-Transmitter Techs in
the building without one of us present. As new men would arrive at the
station, part of the orientation meeting included a demo where we
would use a Hi-Pot to charge up a cap to at least 5KV DC, turn out the
lights and then short it out with a dead man stick. One time we went a
bit overboard with the Hi-Pot and I was left holding a smoking hard
wood handle while my buddy retrieved the metal rod from across the
room. We grabbed another dead man stick and still got quite a bang out
the cap since it didn't completely discharge before blowing up the
other dead man stick.
That one even scared me!
Damn, I never knew they even made caps that big. What was the actual
size of that thing? (roughly). Or is there a photo on the web?
That sounds like quite a charge to see (literally) lol..

Well there is one hell of a difference between 500mf and 1 farad.
Although 1 Farad 5 volt caps have become quite small, one rated at 200
volts might bludgeon them to death if it hits them in the head, charged
or not.
I see no reason this would ever occur, but I'm just curious.
[NOTE: This could be DC or AC]. DC capacitors are used in electronics,

Lots of AC rated caps are used in electronics.
I can only think of two uses.
1. Speaker filter caps (in crossovers)
2. Line caps which are usually very small, such as .05mf. They go across
the power line for voltage surges and spikes.
What are the other uses?

cables connected to a car battery would not likely do anything, or might
just tingle a little (never tried this, but I've handled plenty battery
cables while standing on wet soil in wet shoes and never felt a thing).
Not that I'm planning to test this, but what would happen if a large
capacitor, charged with 200 volts or more was tossed into a filled
bathtub while someone was in the tub? (By large capacitor, I dont mean
the size, but rather, I mean a large capacity, such as 500 MF or one
Farad or more....).
Well there is one hell of a difference between 500mf and 1 farad.
Although 1 Farad 5 volt caps have become quite small, one rated at 200
volts might bludgeon them to death if it hits them in the head, charged
or not.
I see no reason this would ever occur, but I'm just curious.
[NOTE: This could be DC or AC]. DC capacitors are used in electronics,
while the AC type are motor start capacitors.
Lots of AC rated caps are used in electronics.
I can only think of two uses.
1. Speaker filter caps (in crossovers)
2. Line caps which are usually very small, such as .05mf. They go across
the power line for voltage surges and spikes.
What are the other uses?

Ever seen anyone shocked with the deliberator ?
I've never seen a deliberator cause much damage. :)
But a defibrillator works largely because the paddles/electrodes are
placed on opposite sides of the heart. Tough to do with the average
cap without attaching some cables, in which case it would probably
work better out of the tub...

removed from the tv set.
Hurts quite a bit if it discharges through your hand, though.

If you're into analog engineering designs, there are enough to write entire
books on them. Suggest you go research them; not worth trying to make up a
list.
