Copper wire is a

Options

A. Good conductor
B. Poor conductor
C. both a and b
D. None of these

Answer

**Step-by-Step Solution:**

1. **Identify the Material**: Copper wire is made from copper, which is a type of metal.

2. **Understand the Properties of Metals**: Metals are known for their ability to conduct electricity. This is due to the presence of free electrons that can move easily within the metal structure.

3. **Evaluate Copper's Conductivity**: Copper is specifically known to be a good conductor of electricity. This means that it allows electric current to flow through it with minimal resistance.

4. **Conclusion**: Since copper wire is made of copper, and copper is a good conductor of electricity, we can conclude that copper wire is a good conductor.

**Final Answer**: Copper wire is a good conductor of electricity.
