The conductive tissues of the upper leg can be modeled as a 45-cm-long, 14-cm-diameter cylinder of muscle and fat. The resistivities of muscle and fat are 13 m and 25 m,respectively. One person\'s upper leg is 82%muscle, 18% fat. What current is measured if a 2.2 V potential difference is applied between the person\'s hip and knee?

Solution

amount of fat resistance = (25ohms)*(.45m)*(pi)*(.070m^2)*(.18)=..0311
amount of muscle resis = (13ohms)*(.45m)*(pi)*(.070m^2)*(.82)=.0738...

total resistance = .1095ohms
