What do volts measure?

Volts measure electrical pressure, which is a key concept in understanding how electrical energy operates within a circuit. In a sense, voltage represents the force that pushes electric charges through a conductor, much like water pressure in a hose pushes water through. This pressure is crucial because it determines how much current (the flow of electric charge) can be pushed through a circuit when a complete path is available.

Understanding voltage is essential for fire safety inspections, as electrical systems need to operate at appropriate voltage levels to ensure safety and efficiency. When inspecting electrical systems, recognizing the implications of voltage helps in identifying areas where electrical pressure may be too high, potentially leading to overheating or electrical fires if not properly managed.
