Basically DC cannot travel far without being degraded by the very wiring that is carrying it. AC can travel thousands of miles.
Edison wanted DC, Tesla wanted AC.
If Edison had won out, there would be a power generating plant on every block.............
“Basically DC cannot travel far without being degraded by the very wiring that is carrying it. AC can travel thousands of miles.”
Actually the opposite is true, mostly due to inductance in the wire.
There are actually high tension power lines that run vast distances that are DC.
AC is easier to transport long distances because it is easy to increase the voltage to reduce current while still transporting the same power. It is easy to convert AC of high voltage to lower voltages. Converting DC to AC is much more difficult and less efficient.
