Voltage and current for the resistor have a positive linear relationship. As voltage increases, current increases and there is a directly proportional relationship. Voltage is equal to the product of the current and the resistor constant. The parameters in the model are the slope and the intercept because the model is a straight line. The y-intercept is 0 because when the potential difference is zero, the current is also zero. The slope of the graph represents the resistance of the circuit. According to the LINEST function, the slope is 96.20658458 and the intercept is -0.01947332587.
