    not saying that is what killed her, only that it may account for the burns
    the terminals are only mm apart
    so on a wet hand it may see fractions of an Ohm
    so large current, enough to burn

    her body would be in parallel to ground (water/plumbing), so she would see a fraction of that

    But neither the charger nor the USB or lightning connector outbound power from the battery are able to supply more than a couple of amps. And I really do not see a lot of current at only 5V DC.

    And then push that current through human flesh that is pretty high resistance, even when sitting in the tub of water it will still at least be several hundred ohms wouldn't it?

    But "Electrocuted holding a cell phone!" gets a lot more clicks...

    Yes, money matters more than truth these days.

    Yup. It's in the story: The girl's grandmother, who lives in Texas, told the local TV station that's what had happened, and they picked it up and ran with it. But, as the story notes, it happened in New Mexico, not Texas, while the girl was visiting her father. So, she had a burn on her hand, and the phone was in the bathroom. Was the burn fresh? Was it an electrical burn?

    What this story doesn't say (but I saw elsewhere) is that the medical examiner hadn't ruled on the cause of death.

    So, this is just grandma jumping to conclusions.

    It takes 0.1A to cause fibrillation, assuming (generously) 500 ohms resistance of the girl's body in water, it'd take 50V to kill her. But the charger only gives 5V, and it should have been on a GFCI (was it?).

    BTW, cell phones don't cause your car to blow up at the gas station, either. It's the static discharge arc when you touch the pump handle after sliding out of the car seat.

    I see someone else is a Mythbusters fan!

    I miss those guys already. I met them once at their favorite film site (the old Alameda Naval Air Base) about 4 years before they packed it in, they are just like they appear in the show; Jamie is quite and reserved, Adam is animated and outgoing (the younger crew was off somewhere else). But even by then they were getting a little tired of it. Adam said they never thought it would go on as long as it did.

    They would have TOTALLY taken on this issue I think. Did the "new" version of the show ever make it? I know they did a reality competition show to pick the new hosts, then I never heard any more about it.

    Very briefly they had a Hollywood vs Engineers show going, where the teams had to do a build to achieve certain milestones. I think it had half a dozen episodes.

    I miss them too, but when it stops being fun you have to hang it up. You don't want to bring your audience down because it's now just another job. I still don't understand why the axed Grant et al for the final season or so. I thought the A team B team format worked well.

    It was a salary negotiation issue gone awry. The three of them took a page from the Friends and Big Bang cast tactics to stand firm for all of them getting raises, and Discovery called their bluff.
