A) \[1.25\,\Omega \]
B) \[2.5\,\Omega \]
C) \[5.0\,\Omega \]
D) \[10.0\,\Omega \]
Correct Answer: A
Solution :
Key Idea: Potential difference across galvanometer and shunt is same. For G being resistance of galvanometer and \[{{I}_{g}}\] the current across it, the current across S is \[\left( I-{{I}_{g}} \right)\]. Since, \[G\] and \[S\] are in parallel, potential across them is sameYou need to login to perform this action.
