Power dissipated versus load resistance
A circuit consists of a real battery with electromotive force \(\varepsilon\) and internal resistance \(r\) connected across a variable resistor of resistance \(R\). The graph shows the electric power \(P\) dissipated by the variable resistor as a function of \(R\). Based on the graph, what is the electromotive force \(\varepsilon\) of the battery?
