A very long circuit

A large number of AA batteries with emf E=1.5V\mathcal{E}=1.5\, \mbox{V} and resistors with resistance RR form an infinite circuit, as shown in the figure. The internal resistance of the batteries is rr. Thevenin's theorem tells us that this infinite circuit can be replaced by a single source with emf Eeq\mathcal{E}_\text{eq}, connected in series with an equivalent resistor ReqR_\text{eq}. Determine the equivalent emf Eeq\mathcal{E}_\text{eq} in volts if rR=12.\frac{r}{R}=\frac{1}{2}.
