A) \[3.2\times {{10}^{-7}}A\]
B) \[1.6\times {{10}^{-7}}A\]
C) \[0.8\times {{10}^{-7}}A\]
D) none of these
Correct Answer: B
Solution :
Using the relation, \[i=\frac{q}{t}=\frac{ne}{t}\] Here, \[n=1\,billoin\,={{10}^{9}},\,\,\,\,t={{10}^{-3}}\sec \] So, \[i=\frac{{{10}^{9}}\times 1.6\times {{10}^{-19}}}{{{10}^{-3}}}=1.6\times {{10}^{-7}}A\]You need to login to perform this action.
