Which of these allows electricity to pass through it?

Options

A. Glass
B. Wood
C. Rubber
D. Graphite

Answer

### Step-by-Step Solution:

1. **Understanding Conductors and Insulators**:
- To determine which materials allow electricity to pass through, we need to classify them as conductors or insulators. Conductors are materials that permit the flow of electric current, while insulators do not.

2. **Analyzing Each Material**:
- We will examine the materials listed: glass, wood, rubber, and graphite.

3. **Evaluating Glass**:
- Glass is typically an insulator. It does not allow electricity to pass through it. For example, if you try to create a circuit using glass, it will not conduct electricity.

4. **Evaluating Wood**:
- Wood is also an insulator. It does not conduct electricity. If you attempt to pass electricity through wood, it will not allow the current to flow.

5. **Evaluating Rubber**:
- Rubber is another insulator. It is commonly used to cover wires to prevent electric shock because it does not conduct electricity.

6. **Evaluating Graphite**:
- Graphite, on the other hand, is a conductor of electricity. It is made of carbon and has free electrons that can move when a potential difference (voltage) is applied. This allows electric current to flow through graphite.

7. **Conclusion**:
- Among the materials listed (glass, wood, rubber, and graphite), only graphite allows electricity to pass through it. Thus, graphite is the correct answer.

### Final Answer:
**Graphite** is the only material from the list that allows electricity to pass through it.
