How to Carry Out an Experiment to Investigate the Relationship Between Resistance and Wire Length

The video tutorial covers a physics experiment on measuring the resistance of a microwire as its length changes. It begins with an overview of the required equipment and circuit setup, followed by a discussion on the independent and dependent variables, as well as the controls needed to ensure a fair test. The procedure for conducting the experiment is detailed, including safety precautions. Finally, the video explains how to analyze the data using a scatter graph and draw conclusions about the proportionality between wire length and resistance.
