A person with dry skin has a resistance from one arm to the other of about 1x10e5ohms?

When skin is wet, resistance drops to about 1.5 x10e3 ohms.


Table :


1mA mild shock can be felt


5mA shock is painful


15mA muscle control is lost


100mA death can occur





What is the minimum voltage placed across the arms that would produce a current that could be felt by a person with dry skin?


What current would the same voltage produce if the person had wet skin? (answer in mA)


What would be the minimum voltage that would produce a current that could be felt when the skin is wet?
A person with dry skin has a resistance from one arm to the other of about 1x10e5ohms?
Dry resistance is 100000 Ohms


wet resistance is 1500 ohms


1mA=.001A


5mA=.005A


15mA=.015A


100mA=0.1A





E=IR
