Difference between 1-Phase circuit and 3-phase circuit.

Question

Accepted Answer

1-phase circuit has one alternating current waveform, while 3-phase circuit has three alternating current waveforms.

1-phase circuit has single-phase power supply, while 3-phase circuit has three-phase power supply.
1-phase circuit is used for small appliances and residential buildings, while 3-phase circuit is used for industrial and commercial buildings.
1-phase circuit has lower power capacity compared to 3-phase circuit.
In 1-phase circuit, power is delivered through two wires, while in 3-phase circuit, power is delivered through three wires.
Examples of 1-phase circuit include household appliances, lighting, and small motors, while examples of 3-phase circuit include large motors, elevators, and heavy machinery.
