In superconductivity, the resistivity of a material becomes*1 pointZeroFiniteInfiniteNone of the above

The temperature below which the resistivity of a superconductor falls to zero iscalled:A. Absolute temperature ⃝ B. Kelvin temperature ⃝C. Limiting temperature ⃝ D. Critical temperature

The transition temperature Tc of all superconducting materials satisfies the relation*1 pointNone of theseT < TcT = TcT >Tc

The best definition of superconductor is:*1 pointIt is a materials showing perfect conductivity and Meissner’s effect below a critical temperatureIt is conductor having zero resistanceIt is a perfect conductor with highest diamagnetic susceptibilityIt is a perfect conductor but becomes resistive when a current density through it exceeds a critical value

The temperature at which a normal material turns  into a superconducting  state is called the*1 pointCritical temperatureSuperconducting temperatureHigh temperatureLow temperature
