Question

what are the advantages of alternative current over DC current

Answer 1

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.

Answer 2

Advantages of AC Power Over DC. The first advantage AC power has over DC is 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 voltage results in lower current through the power line, and lower current means lower power line losses
