During surgery, a current as small as 20 µA applied directly to the heart may cause ventricular fibrillation. If the resistance of the exposed heart is 300 2, what is the smallest voltage that poses this danger? Smallest voltage that poses danger: Think: Does your answer imply that special electrical safety precautions are needed? = V
