Single phase & three phase line what difference?

Question

Accepted Answer

Single phase and three phase lines differ in the number of conductors and voltage supply.

Single phase lines have two conductors, while three phase lines have three conductors.
Single phase lines are commonly used in residential applications, while three phase lines are used in industrial and commercial settings.
Single phase lines provide a voltage supply of 120V or 240V, while three phase lines provide a voltage supply of 208V, 240V, or 480V.
Three phase lines are more efficient for powering large motors and heavy machinery.
Single phase lines are typically used for smaller appliances and lighting.
