*EST Figure P19.64 shows an I-versus-
V graph for an incandescent lightbulb and a resistor (data are measured separately but presented in the same graph). In one case, the lightbulb and the resistor are connected in series to a 1.5-V battery. Estimate (a) the voltage across the lightbulb and the resistor and (b) the current through the battery. Ignore the internal resistance of the battery. (Hint: The sum of the voltages across the elements is 1.5 V and the current through both elements should be the same.)

(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.
