It only takes 0.1 amps to be fatal.
“It only takes 0.1 amps to be fatal.”
She was not killed by the charging voltage/current of the charger. There are number of reasons why that would not happen in this case. But I won’t go into the science of that. Just remember there is a thing in this entire situation called Resistance that limits the current very much in a low voltage situation.
And also remember her hand was burned.
This girl was killed by AC line voltage. I don’t have knowledge of the the details of the charger So It makes it difficult to nail for sure. But most chargers these days are switching power supply’s. This means no transformer isolation from the 120 volt AC supply. This means that while the voltage between the two wires at the connector that plugs into the cell phone could be 5 volts or less there can still be the potential to kill. Because the voltage between either of the wires and ground can still be around 120 volts. Anyone creating a path between that 120 volts and ground is in for a shock. This is exactly the type of situation that GFI outlets were designed to protect from. They detect that current that should be flowing back through the outlets neutral is actually being lost via another path- most likely to ground.
In any case this was obviously caused by line voltage and line current. She would have been saved either by a GFI outlet or by an analog power supply using a line isolation transformer(assuming she did not contact Where the charger plugs into the AC)
Remember all the power power supplies with with the big black box that plugs into the wall. Those contain transformers that will isolate the output from the AC line voltage and make them safe from this situation.
