A) all cells are connected in series combination
B) all cells are connected in parallel combination
C) 4 cells in each row are connected in series and 6 such rows are connected in parallel
D) 6 cells in each row are connected in series and 4 such rows are connected in parallel
Correct Answer: D
Solution :
For series,\[i=\frac{nE}{nr+R}\] \[i=\frac{24\times 1.5}{24+1.5}=1.41\] For parallel, \[i=\frac{E}{\frac{r}{n}+R}\] \[i=\frac{1.5}{\frac{1}{24}+1.5}=0.97\] For\[4\times 6\]combination \[i=\frac{nE}{R+\frac{nr}{m}}\] \[i=\frac{4\times 1.5}{1.5+\frac{4}{6}}=2.77\] For\[6\times 4\]combination \[i=\frac{nE}{R+\frac{nr}{M}}\] \[\Rightarrow \] \[i=\frac{6\times 1.5\times 4}{12}=3\]
