It’s possible to estimate the percentage of fat in the body by measuring the resistance of the upper leg rather than the upper arm; the calculation is similar. A person’s leg measures 40 cm between the knee and the hip, with an average leg diameter (ignoring bone and other poorly conducting tissue) of 12 cm. A potential difference of 0.78 V causes a current of 1.6 mA.

Required:
What are the fractions of (a) muscle and (b) fat in the leg?
