Description

This lecture introduces a quantity that characterizes a material's resistance by conducting an experiment with wires of varying lengths and diameters, showing that resistance is proportional to length and inversely proportional to section. The instructor demonstrates this graphically and introduces the concept of resistivity, defining the formula for resistance and explaining the significance of resistivity and conductivity in materials. Practical applications and exercises are provided to reinforce the understanding of these concepts.
