High Resistivity Materials | Properties | Applications

High resistivity materials are used for making resistance elements for heating devices, starters for electric motors, resistances used in precision measuring instruments, loading resistances and rheostats and filaments for incandescent lamps.   High resistivity materials are used in all such applications where a large value of resistance is required. If low resistivity materials were used …

Stiffness of Metal

Stiffness of Metal   The resistance of a metal to elastic deformation is called its stiffness of metal. Since the deflections produced in many products by operating loads may affect the workability of the components, the stiffness of the material is often a limiting design factor.   Peculiarly enough, the stiffness of a metal is …

Applications & Properties of Superconductors

Hi friends,   In this article, am discussing properties of superconductors and applications of superconductors. This article will provide you sufficient information about superconductors.   The resistivity of most metals increases with increase in temperature and vice-versa. There are some metals and chemical compounds whose resistivity becomes zero when their temperature is brought near 0° …
