Hi...

Just a question running through my mind. I know that a 12volt car
battery can't electrocute you.

What if i pass it through a step up dc converter to let say 110v for
the or 240v . Would the car battery now electrocute me if i were to
touch the neg and pos since the power supplied by the battery is almost
equivalent to the power supplied by the house electrical power source?

Yes it could hurt you, the difference is that you must touch both
terminals at once since there is no ground path.

Fibrillation (which is what kills you) is perfectly possible with a 12V
battery in the 'right' conditions.

What it takes is 100mA through the heart (an acquaintance of mine got
killed this way doing a charging check on the 28VDC system in a
helicopter many years ago)

As your effective skin resistance varies, it will depend on your
effective resistance being about 80-100 ohms, and the current going
from one set of fingers to the other (so the current path is through
the heart area).

Cheers

110 and 240 is 110 and 240. It can stop your heart or make you stab your
self in the eye with a screwdriver.
Don't think a 12 volt battery can't hurt you. The current can fry your ass.

The way your question is phrased, the answer is no. The 12V from the
battery won't hurt you any more if it's supplying a load than if it's
not (this not counting open wounds (neglibile body resistance), hot
wrenches (you can weld with a 12V battery, under the right conditions),
and that sort of thing, which is a different question). But the 12V is
still 12V.

But the 110 or 240 definitely will at least give you a painful jolt,
and can very easily burn you or kill you.

Hope This Helps!

Fill out your organ donor card and give it a try. Let us know what your

Study some about power.
Measure your body resistance and make calculations of current flow with 12
volts as a source.
Find a chart that shows the effects of current flow through the body.

Respect the potential energy in that battery.
Work safely,

DO NOT MAKE RESISTANCE MEASUREMENTS OF YOUR BODY WITH 12V !!!

As someone else pointed out, it only takes about 100mA through your heart to
kill you -- and maybe less.

Normally, the skin resistance is very high. If you're sweaty the it's less.
If you're under the epidermis then WATCH OUT. Don't take a chance unless you
really know what you're doing.

A few volts arm to arm administered with needles will stop your
heart.

what i meant was after stepping up the battery to a very high voltage
such as 110 or 240 volt... would it kill you if you touch the terminal
at the point after stepping it up? cuz from my guess it should right?
because the voltage is now high enough to penetrate the skin and the
current is also quite big.

Maybe you meant that but that's not what you wrote.
