Why is DC more safe than AC?
Why is DC more safe than AC? That being said, while both are dangerous, AC electricity is more dangerous to work with due to these reasons: The human body has a higher impedance to DC currents than AC; humans can withstand higher voltages of DC electricity than AC.
Does Europe use AC or DC?
Current flowing in power lines and normal household electricity that comes from a wall outlet is alternating current. The standard current used in the U.S. is 60 cycles per second (i.e. a frequency of 60 Hz); in Europe and most other parts of the world it is 50 cycles per second (i.e. a frequency of 50 Hz.).
Why don t Europeans use AC?
Many in Europe resist due to cost, concern about environmental impact and even suspicions of adverse health impacts from cold air currents, including colds, a stiff neck, or worse. Cooling systems remain rare in Nordic countries and even Germany, where temperatures can nudge above 30C for extended periods.
