Which of the cables, one rated 5 A and the other 15 A will be of thicker wire ? Give a reason for your answer.

Explanation

**Step-by-Step Solution:**

1. **Understand the Ratings**: We are given two cables with different current ratings: one rated at 5 A and the other at 15 A.

2. **Know the Relationship**: The thickness of a wire is related to its current-carrying capacity. Generally, a thicker wire can carry more current without overheating.

3. **Compare the Ratings**: The 15 A cable has a higher current rating compared to the 5 A cable.

4. **Conclusion on Thickness**: Since the current rating is directly proportional to the thickness of the wire, the cable rated at 15 A must be thicker than the cable rated at 5 A.

5. **Final Reasoning**: The reason for this is that a thicker wire can dissipate heat more effectively and can handle a higher amount of current without the risk of damage or overheating.

**Final Answer**: The cable rated at 15 A will be of thicker wire than the one rated at 5 A because higher current ratings require thicker wires to safely carry the current.
