Answer:
Electric Fuse is based on the principle of the heating effect of Electric current.
Step-by-step explanation:
The electric fuse is based on the principle of heating due to electric current. As current flows through the wire, heat is produced. As a result of excessive current flow, heat is generated, melting the Fuse, which normally has a low melting point, preventing any damage to an electric circuit and appliances. (I'm sorry if I'm wrong but I think that's it.)
