You might think the probes in the picture are just funny looking ... you aren’t really ever measuring a resistance. You are measuring a voltage and a current. With a four-wire measurement ...

The resistance of an NTC thermistor decreases with increasing temperature. A voltage-current graph for a thermistor is shown below. Voltage - Current graph for a thermistor as current and ...

Record voltage, current and diameter of the wire, d (supplied by the manufacture). Calculate resistance and cross section area, A, in mm 2 (A = \(\frac {{\pi }d^2}{4}\)). Plot a graph of ...
