Question

What type of current can be transmitted great distances?

direct

alternating

Answer 1

Alternating current (AC) can be transmitted over great distances more efficiently than direct current (DC). This is primarily due to the ability of transformers to step up the voltage for long-distance transmission, which reduces losses due to resistance in the wires. While DC has its advantages in certain applications (such as in high-voltage direct current (HVDC) systems), AC remains the standard for most long-distance power transmission.
