1. Name the unit of (a) electrical resistance (b) resistivity2. What is electric fuse? What material is used for fuse wire? |
Answer» <p>1.a) elecrical resistance-ohmb) resistivity-ohm m2.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.Most LV fuse elements are made of copper (Cu). Silver plated copper is also commonly used. As a rule, fuse elements of time delay fuses contain low melting point materials, e.g. tin (Sn) or zinc (Zn) and alloys thereof.</p> | |
