To reduce I-squared x R loss, transmission is done at voltages much higher than what is usable by consumers.  Transformers can easily raise AC voltage for transmission and then lower it for consumption.  The same cannot be done for DC power.

Alternating current is used for transmission because it is easier to transmit AC over high distance at high Voltage levels.It is also more flexible to handle AC at different levels of transformation t...
