Single-phase power is a type of electrical power distribution that uses a single alternating current (AC) waveform. It is commonly used in residential and light commercial applications, providing a simple and efficient way to power household appliances and lighting. The voltage typically used in single-phase systems is either 120 volts or 240 volts, depending on the region. In a single-phase system, power is delivered through two wires: one live (or phase) wire and one neutral wire. This setup allows for a steady flow of electricity, making it suitable for devices that do not require a large amount of power, such as refrigerators, lights, and small motors.
