A) \[10\Omega \]
B) \[15\Omega \]
C) \[10\Omega \]
D) \[3.3\Omega \]
E) \[7.5\Omega \]
Correct Answer: D
Solution :
For meter bridge in balanced state \[\frac{5}{R}=\frac{{{\ell }_{1}}}{{{\ell }_{2}}}=\frac{2}{3},\] where R, is the value of unknown resistance \[\therefore \]\[2R=15,\]or \[R=7.5\Omega \] Hence, the correction option is [d].You need to login to perform this action.
