SUMMARY

The discussion centers on the dangers of electrical shocks, particularly the increased risk when current travels between two hands, as it passes through the heart. Participants emphasize the critical nature of the heart's electrical impulses and the potential for severe consequences. The conversation also references the effects of a Taser, which stimulates sensory and motor nerves, leading to involuntary muscle contractions. A safety rule for working with high voltage equipment is highlighted: keeping one hand behind the back or in a pocket to minimize the risk of a fatal shock.

PREREQUISITES
  • Understanding of electrical circuits and current flow
  • Knowledge of human anatomy, particularly the cardiovascular system
  • Familiarity with the effects of electrical shocks on the body
  • Experience with high voltage safety protocols
NEXT STEPS
  • Research the physiological effects of electrical shocks on the human body
  • Learn about high voltage safety measures and best practices
  • Study the operation and effects of Tasers and similar devices
  • Explore the anatomy of the heart and its electrical conduction system
USEFUL FOR

Electrical engineers, safety professionals, medical personnel, and anyone involved in high voltage environments or studying the effects of electricity on the human body.

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!

So true lol!
