This is Part A of today’s lab, the Carbon Resistor. Many believe this is a linear best fit line with no dynamic portion. Let’s investigate: If a dynamic portion, typically occurs at some place of change. (in this case near 0 Volts) As you see below, the intercepts are different, even though the slopes are generally the same.
Lets look at the data near zero. As we see, the slope is different Results: Positive: 0.629 V/mA or 629 Ohms Negative: 619 Ohms Dynamic: 703 Ohms
Note: The Ohmmeter measured the voltage of this resistor as 620 Ohms
