(a) A defibrillator sends a 6.00-A current through the chest of a patient by applying a 10,000-V potential as in Figure 20.38. What is the resistance of the path?

(b) The defibrillator paddles make contact with the patient through a conducting gel that greatly reduces the path resistance. Discuss the difficulties that would ensue if a larger voltage were used to produce the same current through the patient, but with the path having perhaps 50 times the resistance.
