SUMMARY

The discussion centers on the lethal effects of electrical appliances in water, specifically questioning why a person can be electrocuted when a toaster or radio is submerged. Key points include the misconception that the current would not pass through a person due to the path of least resistance, and the assertion that a significant voltage is necessary to push lethal currents (as low as 5mA) through the human body. The conversation emphasizes the importance of understanding electrical safety, particularly in wet environments.

PREREQUISITES
  • Basic understanding of electrical circuits and current flow
  • Knowledge of electrical safety standards, including RCD (Residual Current Device) functionality
  • Familiarity with human physiology related to electrical shock
  • Awareness of voltage and current relationships in electrical systems
NEXT STEPS
  • Research the function and importance of RCDs in preventing electrocution
  • Study the physiological effects of electrical current on the human body
  • Examine the relationship between voltage, current, and resistance using Ohm's Law
  • Explore safety protocols for using electrical appliances in wet environments
USEFUL FOR

This discussion is beneficial for electrical engineers, safety professionals, and anyone interested in understanding the dangers of electrical appliances in wet conditions.

I've seen this a thousand times and never understood WHY? Someone trying to kill someone drops a toaster/radio whatever into a bath and the bathee fries. Why

The path of least resistance for the current would not be through the person, I would've thought that all that would happen would be the breaker would trip and the person would't feel a thing.

Not considering RCD's at all either I can't see that you would die even without them.

I've read a few things on other websites about the low level current required to kill a human. People are always saying things along the lines of "It only takes 5mA to Kill". A huge voltage is required to push that current through the body so I can't buy that as a reason for being shocked either.

This is not a homework question. You should take this inquiry to an appropriate general forum, or perhaps do some research on the web (Google will help); it's a common enough topic of discussion that you should have little difficulty finding material.
 
I meant to post this in the engineering section.
