How does the effective junction potential barrier change when a p-n junction is reverse biased ?

Explanation

To understand how the effective junction potential barrier changes when a p-n junction is reverse biased, we can break down the explanation into a series of steps:

### Step-by-Step Solution:

1. **Understanding the P-N Junction**:
- A p-n junction is formed by joining p-type and n-type semiconductors. The p-type region has an abundance of holes, while the n-type region has an abundance of electrons.

**Hint**: Remember that p-type has holes (positive charge carriers) and n-type has electrons (negative charge carriers).
