Question: 1 / 400

Which unit measures electric pressure?

Ohm

Volt

The measurement of electric pressure is indicated by the unit known as the volt. In electrical terminology, "voltage" refers to the potential difference in electric charge between two points in a circuit, which can be thought of as the force that pushes electric current through a conductor. The higher the voltage, the greater the potential for electric current to flow.

Understanding electric pressure is essential for estheticians, as many beauty devices used during treatments rely on electrical energy. For example, high-frequency machines and microcurrent devices operate based on specific voltage settings to ensure effective and safe treatments. The other options—ohm, ampere, and watt—represent different electrical concepts. Ohm measures resistance, ampere measures current flow, and watt measures power, which connects current and voltage, but none of these specifically represents electric pressure.
