The electrical conductivity of certain materials changes dramatically as they are cooled to sufficiently low temperatures. In 1911, Heike Kamerlingh-Onnes found that some materials might enter a state where electrical resistance completely disappears. In this workshop, participants will apply Ohm's law and the 4-wire (Kelvin) technique to accurately measure small resistances. They will observe the resistance of a ceramic superconductor material diminish and suddenly disappear completely as the material is cooled down using liquid nitrogen.
