MCQ
The n rows each containing $m$ cells in series are joined in parallel. Maximum current is taken from this combination across an external resistance of $3\Omega$ resistance. If the total number of cells used are $24$ and internal resistance of each cell is $0.5\Omega$ then
- A$m = 8, n = 3$
- B$m = 6, n = 4$
- ✓$m= 12, n = 2$
- D$m = 2, n = 12$
