A) \[\frac{a}{a-b}\]
B) \[\frac{b}{a-b}\]
C) \[\frac{a}{b}\,n\]
D) \[\frac{a+b}{a}\,\]
Correct Answer: B
Solution :
\[n'=n\,\left( \frac{V}{V-{{V}_{S}}} \right)\] \[\Delta n\,\,=\,\,n'-n\] \[=\,\,\,n\frac{V}{v-{{v}_{s}}}-n\] \[=\,\,\,n\left( \frac{{{V}_{S}}}{V-{{V}_{S}}} \right)\] \[\frac{\Delta n}{n}\,\,=\,\,\frac{b}{a-b}\]You need to login to perform this action.
