Analysis
Graph V (y-axis) as a function of I (x-axis). According to Equation (1), the absolute value of the slope of the resulting linear fitting line is I, and the V- intercept is € Determine r and Insert your graph here _
Conclusion State how much is your EMF € and how much is your internal resistance r
