Understanding Resistivity Through Practical Experiments

Last month, a reader of my blog on eleneasy.com asked me a question about the possibility of measuring the resistivity of a powder mixture he created. We initiated a private conversation on the topic, and we ended up agreeing to work together to make such a measurement. He would provide me with the powder he created, and I would make the measurement for him, since he doesn't have the lab resources for such a task.

We also agreed that I would use this opportunity to make a video on how to take this kind of measurements. This is that video.
