A) \[1.2\,\,\Omega \]
B) \[1.0\,\,\Omega \]
C) \[0.8\,\,\Omega \]
D) \[0.6\,\,\Omega \]
Correct Answer: C
Solution :
Given \[{{l}_{1}}=58\,cm,\,{{l}_{2}}=50\,cm\,R=5\] \[\therefore \] \[r=R\left( \frac{{{l}_{1}}}{{{l}_{2}}}-l \right)=5\left( \frac{58}{50}-1 \right)=0.8\,\Omega \]You need to login to perform this action.
