2. A person with dry skin has a resistance from one arm to the other of about 1 x 10^5 Resistance. When the skin is wet, resistance drops to 1.5 x 10^3 Resistance.
a. What is the minimum voltage placed across the arms that would produce a current felt by a person with dry skin?
b. What effect would the same voltage have if the person had wet skin?
c. What would be the minimum voltage that would produce a current that could be felt when the skin is wet?

Not sure why you're asking this question. As the victim of severe electric shock across my chest i learned first hand that the dynamics are highly variable and not studied in detail. It is difficult to convince a lab volunteer to be shocked to fibrillation or "clamp down" which stops the heart. These levels of current also burn muscle and cardiovascular tissues.
Surprisingly, there have been studies.
