Electricity can be a hazard in hospitals, particularly for patients who are connected to electrodes, such as an ECG. 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, the nurse becomes a conductor and a complete circuit can be made through the patient to ground through the ECG apparatus. Calculate the current through the patient:
Bed (low R)
Nurse 10 kΩ
Patient 10 kΩ
ECG apparatus (low R)
Motor 240 V
