Suppose uniusulated copper or aluminium wires are used for flow of electricity from pole to pole in the street. Do you expect a better flow in summer or winter and why?

Explanation

To answer the question regarding the flow of electricity through uninsulated copper or aluminum wires in summer versus winter, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Uninsulated Wires**:
- Uninsulated wires are those that do not have any protective coating. This means that the temperature of the wire can directly be influenced by the surrounding environment.

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