Question

Nichrome or Manganin is widely used in wire bound standard resistors because of their (A) temperature independent resistivity (B) very weak temperature dependent resistivity (C) strong dependence of resistivity with temperature (D) mechanical strength

Tardigrade Admin · Accepted Answer

These materials exhibit a very weak dependence of resistivity on temperature. Their resistance values would be changed very little with temperature as shown in figure. <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/physics/be7b901fb9518ac25f90002be0429e4d-.jpeg" /> Hence these materials are widely used as heating element.
