What is the unit of measurement for electrical strength?

The correct unit of measurement for electrical strength is volts. Volts measure the electrical potential difference or strength in an electric circuit. It represents the force that pushes electric current through a conductor. Understanding the significance of volts is crucial for electrologists as it relates to the effectiveness and safety of electrical devices used during treatments.

Other options, such as ohms, signify resistance, amps denote current flow, and watts represent the power consumed by an electrical circuit. Each of these units has its own specific role in understanding electrical systems, but when it comes to defining electrical strength specifically, volts are the appropriate unit.
