AC versus DC power transmission (2 - Electricity Distribution)

Описание к видео AC versus DC power transmission (2 - Electricity Distribution)

Why is AC used more often than DC? And why are power lines usually at high voltages? Here I explain the history of alternating and direct current and work an example showing how high voltage transmission is more efficient in terms of line losses. Then I relate this to the use of AC for electricity distribution.
