Question
Why is it not advisable to use a piece of copper wire as fuse wire in an electric circuit?

Solution
Due to its high melting point (≈ 1080° C), copper wire is not suited for use as a fuse wire. In addition, regular copper wire is not suitable for use as a fuse because thicker wire is typically available and will not melt under normal conditions.
