Complete the following sentences :
A fuse is a short piece of wire of high........ and of material of low..........

Explanation

To complete the sentences provided in the question, we need to fill in the blanks with the appropriate terms related to the characteristics of a fuse.

1. **Understanding the Function of a Fuse**: A fuse is a safety device used in electrical circuits to prevent excessive current flow, which can cause overheating and potentially lead to fires.

2. **Identifying the Characteristics of a Fuse**:
- A fuse must have **high resistance**. This is important because a high resistance will limit the amount of current that can pass through it under normal operating conditions.
- A fuse must be made of a material with a **low melting point**. This is crucial because when the current exceeds a certain limit, the heat generated will cause the fuse to melt and break the circuit, thus protecting the rest of the electrical system.
