AI Thread Summary
A current shock between two hands is more dangerous than between points on the same arm because it can pass through the heart, a vital organ regulated by electrical impulses. The discussion highlights the risks associated with electrical shocks, particularly emphasizing the dangers of tasers, which induce involuntary muscle contractions by stimulating sensory and motor nerves. A safety rule for working with high voltage equipment is to keep one hand behind the back or in a pocket to minimize the risk of a fatal shock. The conversation also touches on the humorous notion of brain placement in relation to electrical safety. Overall, understanding the pathways of electrical currents in the body is crucial for safety.

Why is a current shock between two hands more dangerous than between two points on the same arm?
 
Physics news on Phys.org
Think about what is between the arms that is a very important organ controlled by electrical impulses.
 
Gotcha. The current must travel through the heart, correct? I was imagining current going from one hand to the other through the air as the primary medium.
 
Nor is a brain to be trifled with.

and
Someone struck by a Taser experiences stimulation of his or her sensory nerves and motor nerves, resulting in strong involuntary muscle contractions.

Some people's brains are located a bit lower down.
 
I have installed, maintained, and repaired many kinds of high power and high voltage equipments during my working career. We survivors have an important rule when working on these, whether you think the power is off or not: ONE HAND BEHIND YOUR BACK or IN YOUR POCKET! Having always obeyed this rule is why I can respond here today.

Well then god forbid a shock goes through both of their feet!
