The principal advantage of ac power over dc power is that
A) more energy is dissipated during transmission.
B) ac circuits multiply power more easily.
C) ac circuits are safer.
D) ac voltage oscillates while dc voltage does not.
E) ac voltage can be transformed via conventional transformers.

Question

Quizplus · Accepted Answer

AC voltage can be easily transformed to higher or lower voltages using transformers, which is crucial for efficient power transmission over long distances. This ability to transform voltage reduces energy loss during transmission, making AC power more advantageous for widespread electrical distribution systems.
