What is the primary difference between single-phase and three-phase systems?

The primary difference between single-phase and three-phase systems lies in their ability to provide a more stable and efficient power supply, which is why the chosen answer focuses on this characteristic.

In a single-phase system, power is delivered through a single alternating current (AC) waveform. This can be sufficient for small loads, like residential lighting and outlets, but the power delivery is not as consistent, especially under varying loads, which can lead to fluctuations in voltage.

Conversely, three-phase systems deliver power through three interconnected AC waveforms that are evenly spaced in phase (each 120 degrees apart). This configuration allows for a more continuous and stable power flow since at least one of the phases is always near its peak voltage. Consequently, three-phase systems can handle larger electrical loads more efficiently, making them ideal for industrial and commercial applications where high power output and stability are crucial.

The other options don't accurately represent this fundamental distinction. Single-phase systems do not utilize three waveforms, which means the first statement is misleading. It's also incorrect to assert that single-phase systems provide more power than three-phase systems, as three-phase systems are typically stronger and facilitate greater power distribution. Finally, while three-phase systems are common in industrial settings, they are not exclusively used for residential
