Title: "Exploring Resistance: Experiment to Determine Resistance per Unit Length of a Potentiometer Wire"

Description:
Join me in this captivating experiment where we delve into the intricacies of electrical resistance by determining the resistance per unit length of a potentiometer wire. In this video, I guide you through the setup of the apparatus, including the potentiometer, jockey, key, standard resistor, voltmeter, and a source of electromotive force, along with the necessary connecting wires.

Step by step, we meticulously set up the experiment, ensuring accuracy and precision in our measurements. I demonstrate how to carefully take values, emphasizing the importance of consistency and attention to detail. With each measurement, we gather crucial data points that will later form the basis of our analysis.

Once the data collection phase is complete, I lead you through the process of plotting a physics graph, showcasing the relationship between potential difference and length along the potentiometer wire. Through meticulous plotting and analysis, we uncover patterns and trends that provide valuable insights into the behavior of electrical resistance.

Finally, we delve into the heart of the experiment, interpreting the plotted graph to determine the resistance per unit length of the potentiometer wire. With keen observation and mathematical precision, we calculate the slope of the graph, extracting meaningful information about the electrical properties of the wire.

Join me on this enlightening journey as we unravel the mysteries of resistance and discover the fascinating world of electrical conductivity.
