Why AC is more reliable than DC?
Why AC is more reliable than DC? AC is easy to be transferred over longer distances – even between two cities – without much energy loss. DC cannot be transferred over a very long distance. It loses electric power.
Is AC or DC better for long distance transmission?
Alternating current is easier to generate and transmitting alternating current leads to lower energy losses than direct current over distances more than a few metres. Although for very long distances (more than 1000 km), direct current can often be better.
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.).
