With reference to semi-conductors answer the following
What is the change in the resistance of the semi-conductor with increase in temperature?

Explanation

To answer the question regarding the change in resistance of a semiconductor with an increase in temperature, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Structure of Semiconductors**:
- Semiconductors have two primary energy bands: the valence band and the conduction band. The valence band is filled with electrons, while the conduction band is where electrons can move freely and contribute to electrical conductivity.

2. **Effect of Temperature on Electrons**:
