AC systems can be which type of configuration?

The correct answer indicates that AC systems can be configured in both single-phase and multi-phase arrangements. Single-phase AC systems are commonly used in low-power applications, such as residential power supply, where a single alternating current pathway suffices for standard devices and lighting. These systems feature a single alternating current waveform.

On the other hand, multi-phase systems, typically two-phase or three-phase, are more prevalent in industrial and commercial applications where higher power and efficiency are required. Three-phase systems, for example, deliver power more evenly, reducing the size of conductors and equipment while enhancing operational efficiency and balancing loads.

The versatility of AC systems to operate in both configurations allows them to be widely utilized across various applications, from simple home wiring to complex industrial installations. This adaptability makes AC systems essential in modern electrical infrastructure.
