If $2\,\text{C}$ of charge passes through a cross-section of a conductor in $4\,\text{s}$, the current is

A$8\,\text{A}$
B$2\,\text{A}$
C$0.5\,\text{A}$
D$0.25\,\text{A}$
Answer & Solution
Correct answer: C. $0.5\,\text{A}$
Using $I=\dfrac{Q}{t}$, we get $I=\dfrac{2}{4}=0.5\,\text{A}$. **So the correct option is C.**
