A material that stops electricity from passing through is called a

• A. Insulator
• B. Conductor
• C. Electricity
• D. Uncharged

Answer: (A)

Electrical resistance is what decides whether electric charge can move through a material. Materials with high resistance resist the flow of electrons and act as insulators. This is why plastics, rubber, glass, and wood can prevent current from passing through and protect us or separate parts of a circuit. In contrast, conductors like metals have low resistance, so electrons move easily and current flows readily. The idea of electricity is the flow of charge, not a material itself, and being uncharged is a state, not a property that makes a material stop current. So a material that stops electricity from passing through is an insulator.
