The patient's bed-rail is coupled to 220V rms above ground through 5 k leakage resistor of the driving electric motor. Patient's right leg is grounded for the ECG measurement with an equivalent resistance of 8 k. A visitor comes and shakes hand with the patient while he is holding the bed rail with his left hand. Assume that the resistance of dry skin 15 k and internal body resistance can be ignored. a) Draw a complete equivalent circuit indicating the paths of leakage currents through the visitor and patient's body; b) Compute the rms currents through the visitor and the patient. Is there a microshock or macroshock hazard, why? The patient's bed-rail is coupled to 220V rms above ground through 5 k leakage resistor of the driving electric motor.
