The electrical resistance of human body

http://van.physics.illinois.edu/qa/listing.php?id=6793Amritha asked:

What is the order of magnitude of the resistance of human body?


The electrical resistance of the human body depends on the condition of your skin at the time of measurement. If your skin is wet, you could have a resistance of only about 1100 Ohms. With dry skin, the amount is much higher at around 495,000 Ohms.

The electrical resistance of your internal body is much smaller at about 85 Ohms up to 575 Ohms.
