What Is the Difference between Alternating and Direct Current?
The difference between alternating current (AC) and direct current (DC) is that in direct current (DC), the electrons travel in one direction while in alternating current (AC), the electrons travel in alternate directions. Alternating current (AC) is used to transport electricity over long distances due to minimal loss. Direct current (DC) was discovered before alternating current.
In alternating current (AC, also ac), the flow of electric charge periodically reverses direction. In direct current (DC, also dc), the flow of electric charge is only in one direction. The abbreviations...
