How would I determine the equivalent resistance of two resistors in series or parallel with this technique?

What was the resistance of the resistor in Part 1? Include your current-voltage plot with the measured slope in your response. Explain how you might determine the equivalent resistance of two resistors in series or parallel with this technique.I got 3.0 Ω as the resistance of the resistor and I was able to make my graph.

Explanation:

By measuring the voltage drop before and after the resistors, and the current in the circuit, you can graph voltage vs current to get a line whose slope is equal to the equivalent resistance.

V = Req × I

For example, if you had two resistors in series, and each resistor was 1.5 Ω, then the equivalent resistance would be 3.0 Ω, and you would get the same graph as if there were a single 3.0 Ω resistor.
