State the characteristics of fuse wire.

Explanation

### Step-by-Step Text Solution:

1. **Definition of Fuse Wire**: A fuse wire is a safety device used in electrical circuits to prevent excessive current flow which can lead to overheating and potential fire hazards.

2. **Material Composition**: Fuse wires are typically made from materials with low melting points, such as lead or alloys of lead. This allows the wire to melt quickly when the current exceeds a certain limit.

3. **Melting Point**: One of the primary characteristics of a fuse wire is its low melting point. When the current flowing through the wire exceeds its rated capacity, the wire melts and breaks the circuit, thus preventing damage to electrical appliances.
