Question

Ohm's law states that the electric potential (E) across any two points is the product of the current (I) and the resistance (R) between those two points (E = IR, 1V = 1A astir 1 Ohm). We want you think about any possible danger to you from the current you generate from your electrochemical cells in this tab. A human can feel a current (I) as small as 5 mA. Dry human shin offers a resistance (R) of about 100,000Ohms. Given this resistance, would you a except to be able to feel a current if you accidentally touched both of the electrodes in any of the cells in this lab simultaneously? Wet skin has a much lower resistance, around 500 Ohms. Would you feel the current with wet skin?

Explanation / Answer

Humans are conductors of electricity. Those are change from person to person.

I1R1=I2R2

0.005 . 100000 =I2 . 500

I2 = 1Amp.

We feel the current with wet skin is 1amp.
