Why Copper wires are used as connecting wires ?

Options

A. Conductivity of Copper is high
B. Resistivity of Copper is high
C. Conductivity of Copper is zero
D. Conductivity of Copper is low

Explanation

To answer the question, "Why are copper wires used as connecting wires?" we can break down the reasoning into clear steps:

### Step-by-Step Solution:

1. **Understanding Conductivity**:
- Conductivity refers to the ability of a material to allow the flow of electric current. A material with high conductivity allows electric current to pass through it easily.

2. **Properties of Copper**:
- Copper is a metal known for its excellent electrical conductivity. It has a high number of free electrons that facilitate the flow of electricity.

3. **Comparison with Other Materials**:
- When selecting materials for connecting wires, metals are generally preferred due to their conductive properties. Copper, in particular, is favored over other metals like aluminum or iron because it has a higher conductivity.

4. **Resistivity**:
- Resistivity is the measure of how strongly a material opposes the flow of electric current. Copper has low resistivity, which means it does not resist the flow of current much, allowing for efficient transmission of electricity.

5. **Conclusion**:
- Since copper has high conductivity and low resistivity, it is an ideal choice for connecting wires in electrical circuits. This ensures that electrical appliances receive the necessary current to operate effectively.

### Final Answer:
Copper wires are used as connecting wires because they have high conductivity and low resistivity, making them efficient for transferring electric current.
