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
$m = 2, n = 12$

✓

Answer

Correct option: C.

$m= 12, n = 2$

$m= 12, n = 2$
