Conductors, Physics

Assignment Help:

Their resistivity is very low and temperature coefficient of resistance is not constant. These are materials with unfilled or overlapping energy bands. Current carriers here are free electron which exists whether external energy is applied or not. At very low temperature or at absolute temperature they become superconductors. Their conductivity increases with decreasing temperature up to near absolute stage.
