Chapter 12, Problem 12.114SP

Interpretation Introduction

Interpretation:

The importance of $77\text{ K}$ temperature in case of superconductors should be determined.

Concept introduction:

Superconductor is a material that can lose its all electrical resistance when lowered to a certain temperature also termed as superconducting transition temperature $\left(T_c\right)$. Two striking properties of superconductor are as follows:

(1) Superconductor can levitate a magnet.

(2) Superconductor can flow current indefinitely with a loss of any energy.
