From data we have that each cell is represented as an ideal 1.5 V battery with a 0.05 Ohms series resistance: dw:1346700404204:dw The total requested voltage is 12V. We can obtain this voltage serially linking together the following number of cells: \[N _{C}=\frac{ V _{T} }{ V _{C} }=\frac{ 12 }{ 1.5 }=8\] dw:1346700632616:dw The battery terminal voltage with a load of 100 Ohm can be obtained with the voltage divider formula: dw:1346700812438:dw

I included the polarities (+ve and _ve) in case of practical connections using the your digital meter probes because I feel it is important
