After skin resistance breakdown, the internal body resistance ranges between which ohms?

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

Answer: (B)

When the skin barrier is breached, the current path switches from the high resistance of dry skin to the much lower resistance of internal tissues. The internal body resistance along that path is typically around 100 to 400 ohms. This range is the standard reference for estimating shock current once skin breakdown has occurred, since muscles, fluids, and other tissues conduct electricity more readily than intact skin. Actual values can vary with contact area, path length, moisture, and whether the current is AC or DC, but the 100–400 ohm range best reflects the low-resistance route through the body after skin breakdown. Values outside this range usually represent scenarios with dry or intact skin or poor contact, not the breached-skin condition.
