The resistance of p-n junction is low when forward biased and is high when reverse biased. Explain.

Explanation

### Step-by-Step Solution:

1. **Understanding P-N Junction:**
- A p-n junction is formed by joining p-type and n-type semiconductors. In p-type, holes are the majority carriers, while in n-type, electrons are the majority carriers.

2. **Forward Biasing:**
- When a p-n junction is forward biased, the positive terminal of the voltage source is connected to the p-side and the negative terminal to the n-side. This reduces the potential barrier at the junction.
- As a result, majority carriers (holes from the p-side and electrons from the n-side) are pushed towards the junction, allowing current to flow easily.
