Conductivity

Without the samples in place, the circuit registered a reading of 480 mA. When the sample is placed in the circuit, a reading of 0mA was obtained, indicating that no current passed through the sample.

Without the sample in place, the reading was 0ohm, meaning that there was no resistance. With the sample in place, the reading obtained was infinite ohms, meaning that there is nearly infinite resistance.

This was repeated for each of our samples, and the same results were obtained each time. This means that our samples have almost infinite resistance and do not allow a current to pass through.
