A) 3.6
B) 2.4
C) 1.1
D) 0.6
Correct Answer: C
Solution :
Given: Balancing length \[{{l}_{1}}=560\,cm\]Change in balance length is \[{{l}_{2}}-{{l}_{1}}=60\,cm\] and resistance (external) \[R=10\Omega \] Internal resistance of the cell is given by \[r=\left( \frac{{{l}_{2}}-{{l}_{1}}}{{{l}_{1}}} \right)R\] \[=\frac{60}{560}\times 10=1.07\approx 1.1\Omega \]You need to login to perform this action.
