voltage
[U] Uncountable
This term describes the electrical pressure that pushes current through a conductor. It is the invisible force or tension that exists before a circuit is closed, similar to the water pressure in a pipe before the valve is opened. In common speech, the word often carries a connotation of danger or intensity. High voltage implies a hazardous environment or a powerful surge, whereas low voltage suggests safety or a delicate electronic component.
Used to describe the general property of electrical potential, such as when discussing the voltage of a power grid.
