Is this the end?

1000 Amps? Pah - You could barely jump start an obstinate donkey with that! 20,000 Amps is more like it.

when we have this type of battery technology, I really wonder why electric car battery technology relies on an array of AA batteries.

That couldn't jump start a squirrel.

I must be honest, in all seriousness it's rather puzzling how these jump starters with such large amperages aren't hideously dangerous.

I'd have thought that even 1000 Amps, let alone 10000 Amps, at 12 Volts across one's torso would be enough to instantly kill someone, and even fry them.

And it can't be that the current flows for only a nanosecond or something, because presumably the current must last a fair time to turn over a large vehicle engine.

The human body has a very high resistance. No matter what the amperage capability of a power supply, 12v will never cause a dangerous electric shock. Try touching both terminals of a car battery (or a jump starter) and you'll be hard pressed to feel anything.

Mains 240v is dangerous because, at this voltage, a few mA (milliamps) will pass through the body.

It is true that current (i) is what kills, and you don't need much current at all, but you need a high voltage (v) to overcome the body's resistance (r).

i = v ÷ r

It's like shooting a building with a gun, voltage is how piercing it is, amps is how much damage it does if it gets inside

Without enough voltage the amps can't get in so no damage

Another example, hold multimeter probes in each hand, measures 0 (or almost 0), current through the body

Stab the probes into each of your thumbs however, and you will die instantly because blood conducts electricity rather nicely

So close to the end of the year and only two nominations for 2019? Sad times

EDIT: Ah...they'll all awaiting final assessment. That's ok then
