The measure of the ability of a material to conduct electricity is called

• A. Bond
• B. Cross-linked
• C. Conventional Cure
• D. Conductivity

Answer: (D)

The main idea is how easily a material conducts electric current. This characteristic is called conductivity, which measures how readily charge carriers move through a material. Conductivity is the reciprocal of resistivity and is expressed in siemens per meter (S/m). Materials with high conductivity allow current to flow with little opposition, like metals; insulators have very low conductivity. At the microscopic level, conductivity depends on how many free charge carriers are available and how easily they can move through the material. The other terms refer to chemical bonding, network structure, or curing processes, not to the material’s ability to carry an electric current, so they don’t describe this property.
