A) 0.027\[\Omega \]
B) 0.054\[\Omega \]
C) 0.0135\[\Omega \]
D) none of these
Correct Answer: A
Solution :
Resistance of galvanometer full scale current \[G=400\,\,\Omega ,\,{{I}_{g}}=0.2\,mA\] \[=0.0002\text{ }A\] \[I=3A\] Required resistance\[S=\frac{{{I}_{g}}C}{I-{{I}_{g}}}\] \[=\frac{0.0002\times 400}{3-0.0002}\] \[=0.027\,\Omega \]You need to login to perform this action.
