Problem: The most important advantage of AC (alternating current) over DC (direct current) is that:A: it is relatively straightforward to change the voltage delivered by an AC source.B: DC results in more power loss in wire than AC.C: electric power can't be delivered by a DC source.D: AC is safer.E: DC could only be used in the early days of electrical power distribution.

FREE Expert Solution

AC allows transmission of current with high voltage, thereby reducing the transmission loss.

Later, this voltage can be stepped down to the desired range for different uses.
