A) \[490\,\Omega \]
B) \[495\,\Omega \]
C) \[395\,\Omega \]
D) \[480\,\Omega \]
Correct Answer: C
Solution :
Let I be the current in the circuit \[4=(5+R)I\] ?(i) According to given condition, \[5\times {{10}^{-3}}=\left( \frac{10}{100} \right)(5)(I)\]\[\Rightarrow \]\[I={{10}^{-2}}A\] ?(ii) Using (i) and (ii), 5+R=400\[\Rightarrow R=395\Omega \]You need to login to perform this action.
