The experiment is repeated again but with six, equal lengths and thicknesses of wire of different materials. Record voltage, current and calculate resistance. A comparison of results in the table ...

We liked [Tom’s] advice from his old instructor: you aren’t really ever measuring a resistance. You are measuring a voltage and a current. With a four-wire measurement, one pair of wires ...

Resistive temperature device (RTD) elements are wire windings or other thin-film serpentines that exhibit changes in resistance with changes in temperature. They are usually made of metallic elements ...
