Chapter 21, Problem 21.103SP

Interpretation Introduction

Interpretation:

To draw a rough plot of electrical resistance versus temperature for YBa₂Cu₃O₇which is a superconductor below its Tc of 90 K and a metallic conductor above 90 K.

Concept introduction:

The superconductor is an element or metallic alloy which when cooled below a certain temperature, the electrical resistance of the material is drastically reduced. This phenomenon is known as the superconductivity and the material is known as the superconducting material.
The temperature below which the material becomes exhibits superconducting behaviour is known as the threshold temperature (T_c).

To draw:

A rough plot of electrical resistance versus temperature for YBa₂Cu₃O₇.
