What is the unit of electrical pressure?

The unit of electrical pressure is the volt. This measurement refers to the potential difference that drives electric current through a circuit. Just as pressure in a water system can drive water through pipes, electrical pressure, or voltage, drives electrons through a conductor.

When voltage is applied across a circuit, it creates an electromotive force that encourages current (measured in amperes) to flow. Understanding this concept is crucial for working with electrical systems, as it lays the foundation for further studying circuit behavior and the relationships between voltage, current, and resistance.

In contrast, watt measures power (energy per unit time), ohm quantifies resistance, and ampere measures the flow of electric current. These terms are essential to electrical engineering but pertain to different aspects of electricity and do not define electrical pressure itself.
