A) 20
B) 11
C) 10
D) 9
Correct Answer: C
Solution :
\[\text{I=}\frac{\text{E}}{\text{nR+R}}\] ?(i) \[\text{10}\,\,\text{I=}\frac{\text{E}}{\frac{\text{R}}{\text{n}}\text{+R}}\] ?(ii) Dividing (ii) by (i), \[\text{10=}\frac{\text{(n+1)R}}{\left( \frac{\text{1}}{\text{n}}\text{+1} \right)\text{R}}\] After solving the equation, \[\text{n=10}\]You need to login to perform this action.
