SUMMARY

The discussion centers on the physiological effects of electric shock, particularly how high voltage can cause muscle contractions that prevent individuals from releasing their grip on the source. Participants clarify that when a person receives an electric shock, the current can lead to involuntary muscle spasms, causing them to hold on rather than being thrown away. It is noted that alternating current (AC) at 120 V, 60 Hz is particularly dangerous as it can induce ventricular fibrillation while exceeding the let-go threshold. The consensus emphasizes the importance of understanding these effects for safety around electrical sources.

PREREQUISITES
  • Basic understanding of electrical concepts, particularly voltage and current.
  • Knowledge of human physiology, specifically muscle contraction mechanisms.
  • Familiarity with electrical safety standards and practices.
  • Awareness of the differences between AC and DC electricity.
NEXT STEPS
  • Research the physiological effects of electric shock on the human body.
  • Learn about electrical safety protocols for working with high voltage systems.
  • Study the differences between AC and DC electricity, focusing on their impacts on muscle response.
  • Investigate the concept of ventricular fibrillation and its relation to electric shock.
USEFUL FOR

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

When a living thing get a current shock then current catch him for sometime and then throw him away?
Why this happen?
Why the wire(or something else from where current is coming) catch him and then thrown him after the current stops or the thing died?
 
Physics news on Phys.org
I haven't seen someone got a real high current shock and thrown away in my life but i'll guess that'd probably be caused by the person's uncontrolled muscle spasms caused by the shock. It's just a guess.
 
its not true that the get caught nd thrown...when u touch a high voltage with ur palm facing the wire you tend to close your hand and contract your muscle(dont ask me y ! i seldom read bio!)...but have you ever seen electricians? they usually test the wires by touching them with fingers with palm not facing the wire...(if the don't have the electrical tester ofcourse:P)...
 
Electricity causes your muscles to contract. You don't get thrown back when you get a shock... Like Santo said, contracting hand muscles with the wire in your palm will actually cause you to hold on and not be able to let go (if the current is high enough). Some people believe that AC is less dangerous because you can somehow let go between the alternations, but I'm not buying it.

I don't recommend trying it, of course :-)
 
Wikipedia says:
A sustained electric shock from AC at 120 V, 60 Hz is an especially dangerous source of ventricular fibrillation because it usually exceeds the let-go threshold, while not delivering enough initial energy to propel the person away from the source.

I'll have to look up some more on this...
