A) \[{{0.5}^{o}}C\]
B) \[{{1}^{o}}C\]
C) \[{{0.1}^{o}}C\]
D) \[{{0.25}^{o}}C\]
Correct Answer: D
Solution :
For minimum deflection of 1 division require current \[=1\mu A\] voltage required \[=iR=1\times 10=10\mu V\] \[\therefore \] \[40\mu V\cong {{1}^{o}}C\] \[10\mu V\cong {{\frac{1}{4}}^{o}}C\] \[={{0.25}^{o}}C\]You need to login to perform this action.
