Question

Suppose that a person's body resistance is 930 Ohm (moist skin). What current passes though the body when the accidentally is connected 120 V? Express your answer to two significant figures and include the appropriate units. If there is an alternative path to ground whose resistance is 39 Ohm. What current passes though the person? Express your answer to two significant figures and include the appropriate units.  If the voltage source can produce at most 1.1 A, how much current passes through the person in the previous case? Express your answer to two significant figures and include the appropriate units.

Explanation / Answer

a) according to ohm's law

I = V/R = 120/930 = 0.13 A

b) I = 120 / 39 = 3.07 A

c) the maximum current that passes would be 1.1 A only
