# [abc] Apple Probes Alleged Deadly iPhone Electrocution. - Page 21

I agree with you, the voltage is too low to do damage. That's what I kinda meant to say, the low volts coupled with body resistance just won't flow enough current to hurt you. There certainly won't be 100 amps flowing from a 12v battery through your body regardless of it's cca rating. That would require a really low .12 ohm load and your body is much higher than that.

For example assume 1000 ohm skin reistance, that works out to only 12 milliamps flowing through you. If your body was a low 300 ohms, still only 40 milliamps flowing through you. The amount of current your body will let flow depends directly on both it's natural resistance and how much voltage is applied (ohms law). You're not regularly touching "12v@100 amps", you're actually only exposed to 12v@ the vicinity of 10-50 mA.

My main point was a battery rated at 100 amps doesn't mean it's going to deliver 100 amps through a circuit no matter what, it will always vary in proportion with voltage and resistance.

Just that is the maximum safe amount of current you can let flow through that battery before risking excessive voltage drop (usually cold cranking amps is the amount of current the battery can deliver for 30 seconds at 0F and not drop below 7.2v), or in the extreme- damage, explosion, etc.

My theory is there is more to this than what the story says...

This is OCN and there are a lot of people with computer/electrical engineering backgrounds on here, so yes we are experts.

The reason why car batteries are 12v and not higher is because of resistance of skin. I would say I have tested that plenty of times. If you have a car or your parents have a car, you can test it as well. Just open the hood and hold only both battery terminals at the same time.
This is exactly the point that the people here don't get the resistance of the skin is extremely high so you need the voltage to pass the skin and get the current trough.
It is like trying to make wood conduct electricity.

Some OCN'ers should have a read in this book(it might be called different in the US):

The book that tells us, everything can be explained and that the true Beta geniuses of the world thought so that you wouldn't have to believe in "stories".

But I digress point being this woman died not because her iphone malfunctioned but because she had a cheap charger which wasn't safe to use on an ungrounded non earth leak protected socket.
It is 100% her fault but we can't blame her after having such an incident, right?
I find the Galaxy exploding in her pocket a funnier story. Overall I say she is just full of it, seems like she has way to much bad luck with phones exploding and shocking her.

Ahh okay interesting, and I hate getting shocked by static, been shocked by the mains a few times but I'm not going to touch a car battery terminal. Thanks though

I always had mine wrapped up in green paper and forgot it during tests (not chem of course)

Current is the amount of electricity flowing, you know. If there's nothing drawing power from your 100amp battery, there's no current flowing. If you grab the terminals on the battery, the resistance of your body is too high to allow any detectable current to flow through your body. Ohm's law 101- its not hard. A high voltage is required to "push" the current through your body. the current rating for a circuit has nothing to do with the amount of current flowing through it, OR for the amount of current that it will provide- 15A household circuits frequently source several times that during motor and transformer startup for a fraction of a second.

If you manage to get even .01 amps flowing through your body from 12v, let me know how you did it, because its almost impossible.

You just repeated what I said but you used more words.
