Which is more dangerous AC or
DC
§ Low frequency (50 –
60 Hz) AC currents can be more dangerous than similar levels of DC current
since the alternating fluctuations can cause the heart to lose coordination,
inducing ventricular fibrillation, which then rapidly leads to death.
§ However any practical
distribution system will use voltage levels quite sufficient to ensure a
dangerous amount of current will flow, whether it uses alternating or direct
current. Since the precautions against electrocution are similar, ultimately,
the advantages of AC power transmission outweighed this theoretical risk, and
it was eventually adopted as the standard.
