Which of the following is an advantage of AC in the distribution of electrical power?

The advantage of alternating current (AC) in the distribution of electrical power is its ability to be transformed from one voltage level to another. This capability is essential for efficient power transmission over long distances. By stepping up the voltage for transmission, the current can be reduced, which minimizes energy loss as heat in the conductors due to resistance. At the destination, the voltage can be stepped down again for safe distribution to homes and businesses.

This transforming ability allows electrical systems to be designed with greater flexibility and efficiency compared to direct current (DC) systems, which do not possess this property as easily. Thus, the capacity to change voltage levels is a key factor that makes AC a preferred choice for power distribution networks.
