Explain briefly with the help of necessary diagram, the forward and the reverse biasing of p-n junction diode. Also draw their characteristic curves in the two cases.

Explanation

### Step-by-Step Solution:

**1. Understanding P-N Junction Diode:**
- A P-N junction diode is formed by joining P-type and N-type semiconductors. The P-type has an abundance of holes (positive charge carriers), while the N-type has an abundance of electrons (negative charge carriers).

**2. Forward Biasing:**
- **Diagram:**
- Draw a diode symbol with P-side (anode) on the left and N-side (cathode) on the right.
