Apple said Monday it would investigate claims that a Chinese woman was killed by an electric shock she received when answering a call while the device was charging.
The claim quickly drew attention after a woman in the western region of Xinjiang wrote about the death of her 23-year-old sister Ma Ailun on China's popular microblog service Sina Weibo.
"We will fully investigate and cooperate with authorities in this matter," said Apple's Beijing-based spokeswoman Carolyn Wu, offering condolences to the family.
She picks up the phone and provides a ground for the electrons.
People keep repeating that but many fail to understand the voltage is the source that determines the amperage when combined the resistance in the human circuit. She got out of the bathtub to answer the phone and was likely dripping wet with very low resistance.
The only way this could happen would be for the wall-wart to fail and pass 220VAC onto the charging cable. Not likely, but possible, I suppose.
And for the service of our readership, it only takes one amp to kill you.
Your average household outlet at 110 volts carries a load of 15 amps. What usually kills you is being 'grounded' too well.
Like sitting in the bathtub while using your Iphone 5, or washing your face in the sink.
I thought that China only made counterfeit products for export, not domestic use. :=)
Where’s the link?
Shocking isn’t it! LOL.
Doesn't matter. The conversion to 5 to 12 vDC occurs in the charger.
Phone made in China with Chinese made parts ...no doubt.
Join the Apple Borg. Resistance is futile.
100-200 milliamps can be fatal.
Actually, it’s the volts and amps both, You can grab both posts of an auto battery, which has 700 or so amps, but only 12 volts, and you won’t even feel it unless you are wet,and then it will be a minor shock. A welding machine with 40 volts and 300 amps available stings pretty good, especially if you are wet. 110 volts and only a few amps can be lethal if all the conditions are right. Spark plug wire voltage is way up, 30,000+, but at only milliamperes will only give you an uncomfortable shock,mostly not dangerous,but may make you bump your head on the hood of your car:). Overhead powerlines here are about 7200 volts, and enough amps to crispy fry you if you get between one of those and a sufficient ground connection.
Liquidation -there’s an App for that.
But....if you put line voltage into your phone, it would most likely explode or catch on fire, or cease working, or something noticeable. For the phone to not only appear normal, but also continue to work, and ring on an incoming call while there was line voltage present in the phone, is pretty unlikely.
And finally, the amount of insulation required to render 120V or 220V safe is pretty small, so even if the wall voltage was present in the phone in some bizarre way that didn't prevent it from working, the phone's plastic case would more than likely be adequate for insulation from shock, let alone electrocution.
I call urban legend.
Not all power supplies isolate the mains power with a transformer. Eg Switched mode.
It is possible for the casing of an appliance to be connected directly to the mains live through a high impedance.
If there is a malfunction inside the Power supply and there is no RF filtering or grounding present and electric shock can occur.
not everywhere. uk is 110v, but 50 Hz, not US 120v 60 Hz.
Was her name Sum Ting Wong, too?
I really don't know.
The higher the voltage, the more insulation required to prevent a fault.
You have a fire waiting to happen. To use the 600W lights in a 28 gauge wire you are going to need ~480V. Depending on the brand, the HDPE insulation in a CAT5 cable is ~0.007" thick. It will withstand that voltage, only for a while. It will breakdown and fault. Maybe it will last a few months, maybe a few years, depending on how often and for how long you use it. If it is lower voltage than that, you are sending more than 1.25 amps down a 28 gauge wire and it is building more heat that the HDPE will withstand over time.
Quit using that piece of crap installation. If you cannot wire it yourself, hire someone that isn't willing to cause a fire.
it would have to be from the energy in the lithium ion batteries surging possibly through the phone, if anything. unless they reported the charging cable smoking/melting.
