Why is a 12-volt household battery harmless, but the shock from 12-volt car battery will kill you ? ​

Answer 1

Answer:

Why is a 12-volt household battery harmless, but the shock from a 12-volt car battery will kill you? ... Sparks (arcing) between a car battery terminal and other metal parts can cause the metal to get hot enough to burn you. If a car battery is short-circuited by a cable, the cable can heat up enough to catch fire

Answer 2

Answer:

Simply put, voltage can be thought of as “pressure,” so while a car battery may technically have enough amperage to kill you, the paltry 12 volts DC simply doesn't provide enough pressure to push any significant amount of amperage through the contact resistance of your skin.
