Electricity can be a hazard in hospitals, particularly to patientsmj69 y u6ojslz72a3t u who mrvaob,76 f *oare connected to electrodes, such as an ECG. 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 th7vo6m oabf* ,re 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 ECG apparatus. This is shown schematically in Fig. 19–60. Calculate the current through the patient. $\approx$ $ \times10^{-3 }\;A$(retain three decimal places)
