[sc_fs_multi_faq headline-0=”h2″ question-0=”What is superconductivity?” answer-0=”The superconductivity phenomenon was first observed by Kemmerlingh Onnes in 1911. In his experiments, he observed that some metal and alloys shows a sudden drop in electrical resistivity when they were cooled down below a certain value of temperature. This phenomenon is known as superconductivity and this material that shows this type of property are superconductors. Remember here, the unit of temperature is Kelvin. As you know 1 Kelvin = -273 degree Celcius. ” image-0=”” headline-1=”h2″ question-1=”What is Critical Temperature?” answer-1=”The normal conductor changes in superconductors when cooled beyond a certain value of temperature. The value of temperature at which normal metal changes into superconductor known as critical temperature. But remember all metals can’t be superconductor like as Si and Ge semiconductors can’t show the optical properties.” image-1=”” headline-2=”h2″ question-2=”” answer-2=”” image-2=”” count=”3″ html=”true” css_class=””]

This is called the critical magnetic field or transition magnetic field. ” image-0=”” headline-1=”h2″ question-1=” Which material was used to investigate the superconductivity by the Heike Kamerlingh Onnes in 1911?” answer-1=”The mercury was used to investigate the superconductivity. Professor Kemerlingh observed that resistance of the mercury dropped from 0.08 Ohm (at about 4K) to less than 3 micro ohm over a temperature interval of 0.01K. This temperature interval is known as the transition width and temperature at which this transition takes place known as the transition temperature of the superconductor.” image-1=”” count=”2″ html=”true” css_class=””]
