simplified electrical model of the human body is showing in

simplified electrical model of the human body is showing in Figures 1 and 2. Assuming that Ra = 400, RT = 50, RL = 200 and a voltage of 250 V exists between one arm and one leg. Apply Ohm’s Law and calculate the current that would flow through the body and determine the likely physiological reaction of the human body. [Hint: The total resistance to the voltage source of Figure 2 is the summation of Ra, RT , and RL.]

Solution

According hint total resistance is 200+50+400

= 650 Ohms

Ohms law V=I*r

I=V/r

250/650

0.3846amp

This much current doesn\'t barriers body so human body
