Bioelectrical 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 estimated. Assume that the muscle and fat tissue can be modeled as resistors in parallel. a) If a potential difference of 5 V is applied across the patient's arm, what is the potential drop across the patient's fat? b) If the measured resistance of the patient's arm is 750 Ω and the resistance of fat is 3 times that of muscle, what is the resistance of the muscle?
