change accordingly. Temperature coefficient of resistivity () is a measure how temperature affects resistivity. We cannot measure resistivity directly- however by measuring the resistance of a wire with an ohmmeter‚ we can calculate the resistivity.

8051 Project: Automatic Lighting and Visitor Counter Andrew Herzog Richard Baker December 13‚ 2007 CMPET 211 Executive Summary The objective of the project was to create a circuit with an 8051 microcontroller that sensed when an object passed through an infrared receiver’s receive path to automatically turn on lights and count how many times the receive path was blocked. Discussion To complete the project several smaller circuits were needed to be designed and constructed. The project

Quality of measurement Write Up Wire Wire This diagram shows how we carried out our experiment‚ by connecting 2 wires to the ohmmeter and attached the wires to the samples we used in our experiment. Preliminary Experiment At first in our preliminary experiment my group and me decided to use an ohmmeter instead of a multimeter. We did this as we thought it would make it easier for us to record our results. These are the results we got from our preliminary experiment: Length (mm)
