## Homework Statement

How can I get the maximum Current Intensity by connecting 72 cells to a 3 Ohm resistor each cell has a potential difference of 1.5 Volt and internal resistance of 1 Ohm

Please don't tell me to connect them all in parallel or all in series as in parallel the potential difference will be low (1.5 Volt) and the resulted current intensity will be approximately 0.49 Amperes and in series the internal resistance will be huge (72 Ohms) and the resulted current intensity will be approximately 1.44 Amperes

**2. The attempt at a solution**

I've tried to connect 18 cells in series and therefore I will have 4 packs of batteries , let's call each pack a battery , so each "battery" has potential difference of 27 Volts and resistance of 18 Ohms , then I connected the 4 batteries in parallel with each other and in series with the resistor , the resulted current intensity was exactly 3.6 Amperes , and that was the best that I can do , anyone have any other better configuration ?

Thanks.
