What happens to Circuits in Liquid Nitrogen? - A Level Physics

This video explains what happens to circuits when they are put into liquid nitrogen for A Level Physics. When an electrical component is placed into liquid nitrogen it cools down very quickly. And the cooler a component is, the less resistance it has. Therefore placing components into liquid nitrogen increases the current flowing through them, which is why the bulb in the video shines brighter. However, if we put the cell or battery in liquid nitrogen then the bulb doesn't shine at all. This is because we have slowed the chemical reaction down in the cell by making it a lot colder.
