A) 20
B) 11
C) 10
D) 9
Correct Answer: C
Solution :
| [c] \[\text{I=}\frac{\text{E}}{\text{nR+R}}\] (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, \[\text{n=10}\] |
