If I is the current in the external resistor R and r is the internal resistance of the cell, the equation for the whole circuit is:
E = I(R + r) …….(i)
For the same current in the external resistor R, the terminal voltage is given by:
V = IR …….(ii)
Use equations (i) and (ii) to solve for r by eliminating I and write this equation the form: y = mx + b Identify the dependent and independent variable
So I made an equation in the form y=mx+b which is r=E*(R/V)-R from the two equations above. If this is right I am unsure of how to graph this equation so that I can find the slope which will be equal to r. I have a table of values of V and R so what values would go on my x axis and what values would go on my y axis? Thanks
