Distinguish between a conductor , a semiconductor and an insulator on the basis of energy band diagrams.

Explanation

To distinguish between a conductor, a semiconductor, and an insulator based on energy band diagrams, we can analyze the characteristics of each material type in terms of their energy bands.

### Step-by-Step Solution:

1. **Understanding Energy Bands**:
- In solids, electrons occupy energy levels that are grouped into bands. The two most important bands are the valence band (filled with electrons) and the conduction band (where electrons can move freely and conduct electricity).

2. **Conductor**:
