As the potential across the resistor increased, the current through the resistor increased. If the change in current is proportional to the potential difference, the data should be in a straight line and the y-intercept should be zero. In the two resistor examples how close is the y-intercept to zero? Is there a proportional relationship between potential difference and current? If so, write the equation for each resistor data set in the form V = mI. Use a numerical value for the proportionality constant, m.

Question
As the potential across the resistor increased, the current through the resistor increased. If the
change in current is proportional to the potential difference, the data should be in a straight line
and the y-intercept should be zero. In the two resistor examples how close is the y-intercept to
zero? Is there a proportional relationship between potential difference and current? If so, write
the equation for each resistor data set in the form V = mI. Use a numerical value for the
proportionality constant, m.
Compare the constant in each of the above equations to the resistance of each resistor.
