An electric fuse is based on
A. The heating effect of the current
B. The chemical effect of the current
C. The magnetic effect of the currentD. None of these

In electronics and electrical engineering, a fuse is an electrical safety device that operates to provide overcurrent protection of an electrical circuit. Its essential component is a metal wire or strip that melts when too much current flows through it, thereby interrupting the current.
An electric fuse is based on the heating effect of the current.
