Interpretation Introduction

Interpretation:

The rough plot of electrical resistance versus temperature for ${\text{YBa}}_{\text{2}}{\text{Cu}}_{\text{3}}{\text{O}}_{\text{7}}$ should be drawn.

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.
