In the event of skin resistance breakdown, the internal body resistance is typically in which range?

• A. 1000-4000
• B. 100-400
• C. 10000-40000
• D. 100000-400000

Answer: (B)

When the skin barrier is breached, the path through the body offers much less resistance than intact skin. This drop in resistance means more current can flow for the same voltage, making the body a much better conductor in that scenario. The internal tissues typically present a relatively low resistance, often described as in the low hundreds of ohms range, so a voltages can push a substantial current through the body. That’s why skin breakdown greatly increases the danger of electrical contact. Ranges that imply much higher resistance would understate the current that can pass, while ranges implying extremely low resistance wouldn’t align with how body tissues conduct electricity.
