How is electrical pressure measured?

Electrical pressure, commonly referred to as voltage, is measured in volts. Voltage represents the potential difference between two points in an electrical circuit, which indicates how much force is pushing the electric current through the circuit. The greater the voltage, the more potential there is for current to flow. This concept is critical in understanding how electrical systems operate, as voltage is a fundamental parameter that governs the behavior of circuits, including how energy is transferred and used.

In the context of the other choices, amperes measure the flow of electric current, watts quantify power, and ohms indicate resistance within the circuit. Each of these quantities plays a unique role in electrical systems, but when it comes to measuring electrical pressure specifically, volts are the relevant unit of measurement.
