Which term describes the property that refers to the ability to conduct an electric current?

• A. Volume
• B. Color
• C. Conductivity
• D. Luster

Answer: (C)

Conductivity is the property that describes how easily electric charges can move through a material when a voltage is applied. It tells you how well a material can conduct an electric current. High conductivity means current flows readily (as in metals like copper); low conductivity means current flow is resisted (as in plastic). The other terms describe appearance or size—volume, color, and luster—not the material’s ability to carry current. Conductivity is an intrinsic material property (the inverse of resistivity) and can change with temperature and structure.
