What is the unit of electrical pressure?

The unit of electrical pressure is the volt. In electrical terms, voltage (measured in volts) represents the potential difference that drives electric current through a circuit. It is analogous to water pressure in plumbing; just as higher water pressure pushes more water through the pipes, higher voltage pushes more electric charge through a conductor. This concept is fundamental in understanding electrical systems, as voltage is what allows current to flow when there is a complete circuit.

The other units listed serve different functions in the electrical system. Watts measure power, or the rate at which energy is consumed or converted, while amps measure the flow of electric charge in a circuit. Lumens, on the other hand, measure the amount of light emitted, which is not directly related to electrical pressure. Understanding these distinctions is key in electrical engineering and applications involving lighting and power systems.
