Question

what kind of material has a high resistivity and prevents the movement of electrons?
a. a wire
b. a battery
c. an insulator
d. a conductor

Explanation:

Insulators have high resistivity, which means they offer significant opposition to the flow of electric current (movement of electrons). Wires (usually made of conductors like copper) have low resistivity and allow electron movement. A battery is a source of electrical energy. Conductors have low resistivity and facilitate electron movement.

Answer:

C. An insulator
