How is electricity defined in the context of nail enhancements?

Electricity in the context of nail enhancements is defined as the movement of electrons from one atom to another along a conductor. This definition is foundational to understanding how electrical currents work, particularly in the use of electric tools and devices employed in nail enhancement services, such as electric nail files or LED lamps used for curing gels.

When electrons move along a conductor, they create an electric current, which is essential for powering the equipment needed in nail enhancements. Understanding this concept allows nail technicians to operate tools effectively and safely, ensuring proper handling and maintenance of the equipment to avoid malfunctions or hazards. The focus on the flow of electrons highlights the importance of proper electrical connections and the materials used in tools, which can affect their performance and efficiency in nail services.

The other choices provide different but related concepts regarding electricity and its applications in the beauty industry, but they do not capture the fundamental definition of electricity itself within this specific context.
