A) 5\[5\,\Omega \]
B) \[4\,\Omega \]
C) \[3\,\Omega \]
D) \[2\,\Omega \]
Correct Answer: C
Solution :
Here: Resistance of galvanometer \[G=6\,\Omega \] Maximum current through the galvanometer\[{{i}_{g}}=2A\] Current in ammeter \[i=6A\] The current through galvanometer is given by \[{{i}_{g}}=\frac{S}{S+g}i\] or \[2=\frac{S}{S+6}\times 6\] or \[25+12=69\] So, \[S=3\,\Omega \]You need to login to perform this action.
