Problem: Variations in the resistivity of blood can give valuable clues about changes in various properties of the blood. Suppose a medical device attaches two electrodes into a 1.2-mm-diameter vein at positions 5.5cm apart.
Part A: What is the blood resistivity if a 9.0 V potential difference causes a 280 Amp current through the blood in the vein?
Please show all work and steps to determine the blood resistivity.
