Question

write some advantages of alternating current over direct current?

Answer 1

Advantages of AC Power Over DC. Thefirst advantage AC power has over DCis in power transmission. ... Both AC and DC have power loss in long lines because of the resistance in the wires. For a fixed power, higher voltageresults in lower current through thepower line, and lower current means lower power line losses.

Answer 2

The major advantage that AC electricity has over DC electricity is that AC voltages can be readily transformed to higher or lower voltage levels, while it is difficult to do that with DC voltages. Since high voltages are more efficient for sending electricity great distances, AC electricity has an advantage over DC.
