Finding resistance in a resistor?

  1. Jun 22, 2009 #1
    1. The problem statement, all variables and given/known data
    Basically, this "battery" is actually a variable voltage source. The current is raised and the voltmeter measures the voltage in the resistor. What is the resistance in the region that the current goes from 1-4 Amps? (BTW, the red line is a best fit line.)

    2. Relevant equations

    3. The attempt at a solution
    Ok, well since this is linear, the slope of this line is actually V/I, so would the slope of the line be the resistance?

    Yes it would be the slope of the line.
