  1. Question 1

    Q1. Copper is a good electrical conductor mainly because it has what feature?

    • A) Many mobile charge carriers that can move under a field
    • B) No atoms at all
    • C) Permanent north poles only
    • D) Zero temperature always

    Answer: Many mobile charge carriers that can move under a field

    Explanation: Copper has a single loosely bound valence electron per atom that is free to move through the metal lattice as a conduction electron when an electric field is applied, giving copper its high electrical conductivity.
