A) \[4\times {{10}^{-1}}\,volt\]
B) \[2\times {{10}^{-3}}volt\]
C) \[4\times {{10}^{-3}}volt\]
D) \[2\times {{10}^{-1}}volt\]
Correct Answer: C
Solution :
Error in measurement = Actual value ? Measured value Actual value = 2V \[i=\frac{2}{998+2}=\frac{1}{500}A\] Since \[E=V+ir\] Þ \[V=E-ir=2-\frac{1}{500}\times 2=\frac{998}{500}V\] \ Measured value \[=\frac{998}{500}V\] Þ Error\[=2-\frac{998}{500}=4\times {{10}^{-3}}volt\]You need to login to perform this action.
