. . . . . . V Part A Bloelectrlcal Impedance analySIs Is a commercially available method used to estimate body fat ./ percentage. The device applies a small potential between two parts of the patient's body and measures the current that flows through. With an estimate of the resistance individually of the muscle and fat between the two points, the composition of the tissue can be If the resistance of fat is 3 times that of muscle, what is the resistance of fat if a 1 mA current is measured when potential difference of 0.5 V is applied to the patient's arm? estimated. Assume that the muscle and fat tissue can 1500 Q be modeled as reSIstors In parallel. 2000 Q 375 9 500 9 Previous Answers v Correct v PartB v If the resistance through the fat is 3 times that through the muscle, how much 01 the total current goes though the fat in terms of the current through the muscle? 3 times the current through the muscle The same current as through the muscle No current passes through the fat. % times the current through the muscle Bioelectrical impedance analysis is a commercially available method used to estimate body fat percentage.
