Question

copper wire is an example of
a. a conductor.
b. a circuit.
c. a nonconductor.

Explanation:

To solve this, we analyze each option:

• Option A: A conductor is a material that allows electric current to flow easily. Copper is a metal known for its high electrical conductivity, so copper wire is a conductor.
• Option B: A circuit is a closed path for electric current, but a copper wire alone isn't a circuit (a circuit needs components like a battery, resistors, etc., connected in a loop).
• Option C: A nonconductor (insulator) is a material that doesn't allow current to flow easily (e.g., rubber, plastic). Copper is not an insulator.

Answer:

A. a conductor
