The effective resistance of two 2 ohm resistance is 
1 half plus fraction numerator begin display style 1 end style over denominator begin display style 2 end style end fraction equals fraction numerator begin display style 1 end style over denominator begin display style R end style end fraction R equals 1 capital omega
Now all the resistance are connected in series including the internl resistance(1 ohm) of the cell.
4+1+2+1=8ohm
