Neha has lost one of the wires of her elecric circuit.Which of these items can she use to complete her circuit?

Options

A. Iron nail
B. Plastic straw
C. Dried wooden twing
D. Glass strip

Answer

To determine which item Neha can use to complete her electric circuit after losing one of the wires, we need to analyze the properties of the materials listed.

### Step-by-Step Solution:

1. **Identify the Requirements of a Circuit**:
- An electric circuit requires a complete path for electric current to flow. This path is typically made up of conductive materials (wires).

2. **List the Items Available**:
- Neha has the following items to choose from:
- Iron nail
- Plastic screw
- Wooden twig
- Glass strip

3. **Evaluate Each Item for Conductivity**:
- **Iron Nail**: Iron is a metal and a good conductor of electricity. It can effectively allow electric current to pass through.
- **Plastic Screw**: Plastic is an insulator and does not conduct electricity. Therefore, it cannot be used to complete the circuit.
- **Wooden Twig**: Wood is also an insulator and does not conduct electricity well. It cannot be used in the circuit.
- **Glass Strip**: Glass is a poor conductor of electricity (an insulator) and cannot be used to complete the circuit.

4. **Conclusion**:
- Among the items listed, the only one that can be used to complete the circuit is the **iron nail** because it is a good conductor of electricity.

### Final Answer:
Neha can use the **iron nail** to complete her electric circuit.
