Resistivity
P=RA/L



Description of the qualiative effect of temperature on
the resistance of metal conductors and thermistors.
Applications (temperature sensors)
Superconductivity as a property of certain materials
which have zero resistivity at and below a critical
temperature which depends on the material.
Applications (e.g. very strong electromagnets, power
cables)
Circuits…
