Chapter 21, Problem 21.115CHP

Interpretation Introduction

Interpretation:

The speciality of temperature $\text{77K}$ for superconductors has to be given.

Concept introduction:

Superconductor:

A superconductor is defined as a material which loses resistance of electricity below particular temperature known as superconducting transition temperature ${\text{T}}_{\text{c}}$.  Below ${\text{T}}_{\text{c}}$, superconductor changes to good conductor and electricity flows continuously.
