Adc current of 60 ma can cause paralysis of the body's respiratory muscles and hence interfere with breathing, but only 15 ma (rms) of ac current will do the same thing. suppose a person is working with electrical power lines on a warm humid day and therefore has a low body resistance of 1100 ohms. what dc and ac (amplitude and rms) potentials would it take to cause respiratory paralysis?
