What is meant by the voltage of a system, and how does voltage flow through a current?
Meaning of system voltageDefinitionSystem voltage is the potential difference between specific points in an electrical system (such as a power supply system, an electronic circuit system, etc.). In power systems, it usually refers to the voltage between a certain phase or line in the grid. For example, in a three-phase four-wire low-voltage distribution system, the phase voltage (the voltage between the live line and the neutral line) is 220V, and the line voltage (the voltage between the live l
