Electrical appliances with metallic bodies which provides a conducting path to the flow of current, in case there is an accidental leakage of current through the conducting body of the appliances.
ii. An electrical fuse is a safety device that operates the overflow of current in an electrical circuit. An important component of an electrical fuse is a metal wire or strip that when excess current flows through it.
