Which statement most accurately describes a conductor versus an insulator in the context of salon electrical safety?
Explanation
A conductor is a material through which electric current flows readily; an insulator resists current flow. Copper wiring carries current in tools; water and the moist human body conduct electricity, which is exactly why GFCI protection is required where water and electricity meet. Rubber, dry wood, glass, and silk insulate, which is why tool handles are rubber and the technician should stand on a dry floor. California regulates safe equipment use under CCR Title 16 §979.2. Option A reverses the categories. Option C is the opposite of physical reality. Option D treats conductivity as binary; it is a continuum and copper is the practical workhorse conductor.
