Circuit schematic with internal resistance and variable load.
A battery with electromotive force \(\mathcal{E}\) and non-zero internal resistance \(r\) is connected in series with a variable load resistor of resistance \(R_L\). As the resistance \(R_L\) is varied from zero to values much greater than \(r\), the electric power \(P_L\) dissipated by the load resistor changes. Which of the following graphs best represents \(P_L\) as a function of \(R_L\)?
