An adhesive designed to reduce electrical current flow using a carbon black additive is best described as which type of adhesive?

• A. Conductive Adhesive
• B. Non-conductive Adhesive
• C. Epoxy Adhesive
• D. Structural Adhesive

Answer: (B)

The main idea tested here is how additives affect the electrical behavior of an adhesive. If the goal of the adhesive is to reduce electrical current flow, it is meant to act as an insulator, resisting the passage of electricity. While carbon black is often used to create conductive paths in some formulations, the description given specifies a purpose of limiting current, which aligns with non-conductive (insulating) behavior. The terms epoxy or structural describe the chemical family or mechanical role, not the electrical behavior, so the key classification is based on its insulating nature.
