What is the typical range of human body resistance?

• A. 500 to 1,000 ohms
• B. 5,000 to 10,000 ohms
• C. 50 to 1,000,000 ohms
• D. 50,000 to 100,000 ohms

Answer: (A)

The typical range of human body resistance is important in understanding how electrical currents interact with the human body. The correct choice indicates that human body resistance generally falls between 500 to 1,000 ohms. This range can vary based on several factors, including skin condition, moisture, and the points of contact on the body, but this value is commonly accepted in electrical safety discussions. Resistance in this range can significantly influence how electrical currents can affect the body in situations of exposure to electric shock. For instance, lower resistance values can lead to more dangerous currents passing through the body, increasing the risk of injury. The understanding of this resistance is critical for Biomedical Equipment Technicians, as it helps in the assessment of safety standards related to medical devices that generate electrical currents. Higher or lower values mentioned in other options significantly deviate from the commonly accepted range for intact human skin and do not represent typical scenarios encountered in practical electrical safety evaluations.
