A) \[0.5{}^\circ C\]
B) \[1{}^\circ C\]
C) \[0.1{}^\circ C\]
D) \[0.25{}^\circ C\]
Correct Answer: D
Solution :
[d] For minimum deflection of 1 division require current \[=1\mu A\] |
voltage required \[=iR=1\times 10=10\mu V\] |
\[\therefore \] \[40\mu V\cong {{1}^{o}}C\] |
\[10\mu V\cong {{\frac{1}{4}}^{o}}C\] |
\[={{0.25}^{o}}C\] |
