In electrical safety, what does the term "pressure" refer to?

In electrical safety, the term "pressure" refers to voltage. Voltage represents the potential difference between two points in an electrical circuit and can be thought of as the force that pushes electric current through a conductor. This "pressure" is essential for electrical current to flow, much like water pressure pushes water through pipes.

Understanding voltage is crucial for safety, as high voltage levels can lead to electric shock and other hazards. Proper recognition and management of voltage levels help ensure safe practices when working with electrical systems.

Current, resistance, and frequency are related electrical concepts but do not correspond to the term "pressure" in this context. Current refers to the flow of electric charge, resistance measures how much a material opposes that flow, and frequency indicates how often an alternating current changes direction. However, these terms do not encapsulate the concept of "pressure" in the same way that voltage does.
