SUMMARY

The discussion centers on calculating the minimum voltage required to induce ventricular fibrillation when a person touches an electric appliance while bathing. The total resistance through the person's body is stated as 3097 Ohm. Using Ohm's Law (V=IR), the critical current threshold for ventricular fibrillation is noted to be approximately 0.7A. Therefore, the minimum voltage that could cause this condition is calculated to be around 2178.9 volts (V = 0.7A * 3097 Ohm).

PREREQUISITES
  • Understanding of Ohm's Law (V=IR)
  • Knowledge of electrical resistance and current
  • Familiarity with the physiological effects of electric shock
  • Basic concepts of ventricular fibrillation and its thresholds
NEXT STEPS
  • Research the physiological effects of electric shock on the human body
  • Study the electrical safety standards for appliances in wet environments
  • Learn about the thresholds for ventricular fibrillation and cardiac arrest
  • Explore the implications of electrical resistance in medical emergencies
USEFUL FOR

Electrical engineers, safety professionals, medical personnel, and anyone involved in electrical safety and emergency response scenarios.

Electricity problem.Pleae help!

Suppose a person touches the case of an electric appliance while taking a bath. The total resistance through the person's hand and body is 3097 Ohm. What is the smallest voltage on the case of the appliance that could cause ventircular fibrillation? Any help would be great!

I've been trying to use V=IR but what is the current? Please help!

Probably very few people here, if any, know the biological aspects of this problem. If you asked us how much current would flow for any given voltage, you could get an answer. What does it take to cause ventircular fibrillation? I assume the source of the question covers that topic somewhere.
 
I've heard 0.7A is the most the heart can take.
