(a) In Exercise 48, suppose instead the case had been properly wired and grounded as shown in Figure 18.23. If the grounding wire had a total resistance of 0.10-Ω, what is the ratio of the current in you to the current in the ground wire, assuming that the fuse/ circuit breaker does not “trip.”
(b) Show that there is enough current to “trip” it, thus safely opening the circuit, reducing the current to zero (almost immediately), and probably saving you from serious injury.
