Question: Derive an expression for the linear battery model power output as a function of the internal-to-external resistance ratio. Nondimensionalize the power output by dividing it

Derive an expression for the linear battery model power output as a function of the internal-to-external resistance ratio. Nondimensionalize the power output by dividing it by $E^{2} / R_{i}$. Tabulate the dimensional power function with a spreadsheet and then plot it. At what point is the maximum nondimensional power achieved?
