poor conductors are

Options

A. Plastics
B. Clothes
C. Wood
D. All of these

Answer

**Step-by-Step Solution:**

1. **Understanding the Concept of Conductors and Insulators:**
- Conductors are materials that allow electric current to flow through them easily. Examples include metals like copper and aluminum.
- Insulators are materials that do not allow electric current to flow through them easily. They resist the flow of electric current.

2. **Defining Poor Conductors:**
- Poor conductors are materials that do not allow electric current to pass through them efficiently. They can be considered as insulators.

3. **Identifying Poor Conductors from the Options:**
- The options given are Plastic, Clothes, Wood, and All of These.
- We need to analyze each option to determine if they are poor conductors.

4. **Analyzing Each Option:**
- **Plastic:** This is a non-metallic substance and is known to be a poor conductor of electricity. It is commonly used as an insulator.
- **Clothes:** Typically made from fabrics (like cotton or polyester), clothes also do not conduct electricity well, making them poor conductors.
- **Wood:** Wood is another non-metallic substance that does not conduct electricity effectively, thus it is also a poor conductor.

5. **Conclusion:**
- Since all the given options (Plastic, Clothes, and Wood) are poor conductors of electricity, the correct answer is "All of These."

**Final Answer:**
All of these (Plastic, Clothes, Wood) are poor conductors.
