Can You Electrocute Yourself on the Lightning Plug?

1V can't create 10A in a human body. Human bodies electrical resistance is about 1000 Ohms. Electricity becomes dangerous from 50mA upwards, that calculates to about 60V or more.
You need voltage to create current. No voltage, no current. If you touch your car battery, which can created probably 1000A for a short time you will be exposed to 12V, which creates a mediocre 12mA.
Static electricity can be very high, many 1000's of volts, but the energy level is very low.
I think the cats USB plug is under its tail.
landline was standardised minus 48 volts DC (current limited to around 50 milliamps) but the ringing waveform is 70 to 100 volts AC at around 100 hertz superimposed on the DC. that's 100 x hurts!
Do our schools teach basic things like what voltage, wattage and amperage actually is. It amazes me how the OP could ask a question like this.
What are they teaching in schools?

For 2A to flow at 5V you would have to have a resistance of 2.5 ohms, and you are not going to find that on the human body, even the tongue...

Not at my school they didn't
The voltage from the lightening connector is very low, even if you tripped and landed tongue first on the thing you would, at most, get a tingle..
An interesting post came out the other day about how much it actually costs to charge the iPhone 5 for a whole year. They found on average the cost was $0.41/£0.25 a year.

Just wear these little yellow boots and you'll be fine. They'll double to protect you from the radiation emitted too!
Good info, I know it didn't feel good. LOL

No they aren't. That isn't on the standardized tests or in the curriculum that the states have dictated. In order for students to get that info they need to take some sort of a career center class like automotive, electronics or welding (I teach it in my automotive class) but with the higher and higher academic demands being put on our students, they have less and less time in school to take real world elective classes because according to the politicians, that knowledge is not needed and everyone is going to college to work in the corporate world and will never need that information.
Yes, thanks for letting us all know you didn't sleep though highschool physics. However here in the real world, it is humans being electrocuted. Humans have impedance. Therefore the combination of amperage And voltage is what is relevant, amps without volts can't kill you and vice versa.
All of this is academic anyway. As I said in simple terms, the 5v 2amp combo across contacts .5mm apart will not hurt any human.
Not in the UK they aren't .... since the iP5 launch I've been to my local store about 4-5 times and every time there's been a wall-full of them.
No issues to report here. Seems fine to me... I know in that explanation of the lightning cable we saw last week, it talked about this:
"The device watches for a momentary short on all pins (by the leading edge of the plug) to detect plug insertion/removal."

Which could help explain why you don't get electrocuted by the lightning cable. I'm no expert on this stuff though.
