This document discusses different electrical engineering materials including fuses, resistors, and conducting materials. It explains what a fuse is and fuse ratings like rated carrying current and fusing time. It also lists different metal fuse elements and fusible alloy compositions and melting points. Resistors are described as integral circuit components, and materials used for precision and potentiometer resistors are covered. Conducting materials applications include transmission lines, electrical machines, transformers, DC machines, induction motors and synchronous generators.

2. FUSES
2
 What is the fuse?
 Rated carrying current of fuse
 Fusing Current
 Fusing Time
 The fusing time is found from the relation
 The rating of any fuse depends on dimensions, enclosures, etc.

3.  Metals and their melting points which are
used as fuse elements.
 Composition and melting points of some
fusible alloys
 Types of fuses

4. RESISTORS
4
