Experiment on the Characteristics of a Resistor and Ohm's Law

The video tutorial demonstrates an experiment to investigate the relationship between current and potential difference across a fixed resistor. Matt constructs a circuit, measures current and voltage, and records the data. He then reverses the current direction to observe changes. The results are plotted on a graph, showing a linear relationship, indicating that current is directly proportional to potential difference. The experiment concludes with the calculation of resistance, reinforcing the concept of Ohm's Law.
