Finding Resistance: Investigating the Relationship between Resistance and Length of Nichrome Wire

The video tutorial demonstrates an experiment to investigate the relationship between the resistance and length of a nichrome wire. Catherine replaces a fixed resistor with a nichrome wire, measures the current and potential difference, and records the data. By varying the wire length, she calculates resistance using Ohm's Law and plots the data on a graph. The results show that resistance is directly proportional to the wire's length, confirming the linear relationship.
