A) 1
B) 0
C) 2
D) None of these
Correct Answer: B
Solution :
\[\delta ={{\tan }^{-1}}\left( \frac{2}{\sqrt{3}} \right)\] \[R=\frac{\Delta V}{\Delta l}=\frac{2.3-0.3}{10\times {{10}^{-3}}}\] \[R=\frac{2}{10\times {{10}^{3}}}\] \[R=0.2\times {{10}^{3}}\Omega \] = 0 ( \[R=0.2\times {{10}^{3}}\Omega \] two rows are identical)You need to login to perform this action.
