Electricity can be a hazard in hospitals, particularly to patients who are connected to electrodes, such as an EGG. For example, suppose that the motor of a motorized bed shorts out to the bed frame, and the bed frame€™s connection to a ground has broken (or was not there in the first place). If a nurse touches the bed and the patient at the same time, she becomes a conductor and a complete circuit can be made through the patient to ground through the EGG apparatus. This is shown schematically in Fig. 19-60. Calculate the current through the patient.
