A) \[48\Omega \]
B) \[32\Omega \]
C) \[40\Omega \]
D) \[44\Omega \]
Correct Answer: B
Solution :
[b] \[For\text{ }1\text{ }cm\text{ }V\text{ }=\text{ }{{10}^{-3}}\text{ }volt\] \[For\,400\,cm,V=={{10}^{-3}}\times 400\] \[V=0.4\text{ }volt\] \[V=\frac{2}{8+R}\times 8\] \[0.4=\frac{16}{8+R}\] \[40=R+8\] \[R=32\Omega \]You need to login to perform this action.
