Single phase and three phase refer to the different types of electrical power supply systems. Single phase systems have only one phase and are commonly used in residential and small commercial applications. They are suitable for powering small appliances, lighting, and heating systems. On the other hand, three phase systems have three separate phases and are typically used in industrial and commercial settings. They provide a more balanced power distribution and are suitable for powering heavy machinery, large motors, and industrial equipment.
