What is the minimum required voltage for a person to experience a lethal electric shock?

• A. 20 volts
• B. 50 volts
• C. 100 volts
• D. 150 volts

Answer: (B)

The minimum required voltage for a person to experience a lethal electric shock is generally recognized to be around 50 volts. This is significant because, at this voltage level, the electric current can overcome the body's natural insulation and potentially lead to serious injury or fatality. When current flows through the body, it can disrupt the normal electrical signals in the heart and lead to ventricular fibrillation, which is a life-threatening condition. While lower voltages can also be dangerous under specific conditions (like wet skin or when contact is made with the ground), 50 volts is the threshold often cited in safety standards as the point where electric shock becomes particularly hazardous, especially in wet or conductive environments. Understanding the implications of voltage in relation to electrical safety helps individuals prevent accidents and respond effectively to potential electrical hazards.
