Two conducting wires X and Y of same diameter but different materials are joined in series across a battery . if the number density of electrons in X is twice that in Y . Find the ratio of drift velocity of electrons in the two wires. (Adithya Singh asked this) Incoming search terms:i want to [...]

# what is the thermal conductivity of a perfect conductor?

Soumya asked: "What is the thermal conductivity of a perfect conductor?" Ans: Please check the link below for a detailed list of thermal conductivities of different materials. http://en.wikipedia.org/wiki/List_of_thermal_conductivities Every good conductor has some thermal conductivity - low or high. Just like superconductor, thermal conductivity may become infinity for a Thermal Superconductor. Thermal Superconductors may become a reality using CNT … Continue reading what is the thermal conductivity of a perfect conductor?
