Which type of current is best for sending electrical energy from one location to another? Why?

Question

Direct current, because it can be produced from batteries.
Direct current, because it moves in one direction.
Alternating current, because its voltage can be easily raised.
Alternating current, because it uses a lower voltage

Answer 1

Alternating current (AC) is typically considered the best type of current for sending electrical energy from one location to another over long distances. This is because AC voltage can be easily changed (transformed) using transformers, allowing it to be transmitted at higher voltages over long distances with less power loss through resistance than direct current (DC). Additionally, AC generators are simpler and more efficient to produce and operate than DC generators. Therefore, while DC can be useful in certain applications, AC is generally preferred for power transmission.
