Property measuring how well a material conducts electricity
ρ=RAL\rho = \frac{RA}{L}ρ=LRA
Resistance increases as temperature rises
Atoms vibrate more, more collisions, slower electron flow
Resistance decreases as temperature increases
Temperature sensors in circuits (control heaters/fans)
Material with zero resistivity below critical temp.
Close to absolute zero (-273°C)
Transmit electricity with no energy lost to heat
Generate magnetic fields for frictionless motion
