Question

7. The resistance of dry human skin is about 500,000 ohms in wet, sweaty

human skin is about 1000 ohms. How much current passes across
someone's finger if they touch the leads of a 9 volt battery when their skin
is wet and dry?

Answer 1

Explanation:

1000 Ohms

R = 1000

V = 9

I = V / R

I = 9 / 1000

I = 0.009

500000 Ohms

V = 9

I = V/R

R = 500000

I = 9 / 500000

I = 0.000018
