Interaction of charges is known as :

Options

A. Lightening
B. Electrical discharge
C. Earthing
D. Electricity

Answer

**Step-by-Step Solution:**

1. **Understanding Charges**: Begin by recognizing that there are two types of electric charges: positive and negative. These charges can interact with each other.

2. **Identifying Interaction**: The interaction of charges refers to how these positive and negative charges influence each other when they come close together.

3. **Example of Lightning**: A common example of charge interaction is lightning. During a thunderstorm, clouds accumulate charges. The upper part of the cloud tends to gather positive charges, while the lower part accumulates negative charges.

4. **Ground Charges**: Additionally, the ground beneath the clouds also gathers positive charges. This creates a significant difference in charge between the clouds and the ground.

5. **Role of Air**: The air acts as an insulator between these charges. However, when the difference in charge becomes too great, the air can no longer insulate, leading to a discharge of electricity.

6. **Formation of Lightning**: This discharge results in a rapid movement of charges, which we observe as lightning. Thus, the interaction of these charges results in a visible phenomenon.

7. **Conclusion**: Therefore, the interaction of charges is known as lightning.

**Final Answer**: The interaction of charges is known as **Lightning**.
