A single-phase power supply provides alternating current electrical power in a system in which all voltages vary in the same pattern. This sort of distribution is most common when the power load is primarily used for lig... More »

A three-phase power supply is a special method to alternate power generation, transmission and distribution. This method establishes power supply delivery in three lines, and each line is a phase that carries equal volta... More »

According to the Electrical and Computer Engineering Department of Kansas State University, a single line diagram is a simplified way of diagramming a three-phase power system. It is also called a one-line diagram. More »

A parallel LC circuit is in resonance when a current detected through the parallel circuit falls in phase with the supply voltage, according to Electronic-Tutorials. At the point of resonance, a large circulating current... More »

An electric light bulb works by conducting an electric current through its wires and the filament once it gets connected to a power supply. As the current flows through the components of an electric bulb, it generates li... More »

Single-phase power propagates as a single waveform, with intermittent peaks in power occurring at regular intervals, while three-phase power propagates as three distinct waveforms, with intermittent peaks in power occurr... More »
