What current is flowing in a wire if $0.67 \mathrm { C }$ of charge pass a point in the wire in $0.30 \mathrm {~s}$ ?
A) $2.2 \mathrm {~A}$
B) $0.20 \mathrm {~A}$
C) $0.30 \mathrm {~A}$
D) $0.67 \mathrm {~A}$

Current is calculated by dividing the charge by the time it takes for that charge to pass a point, which is $I = \frac{Q}{t} = \frac{0.67 \, \mathrm{C}}{0.30 \, \mathrm{s}} = 2.23 \, \mathrm{A}$, rounding to one decimal place gives $2.2 \, \mathrm{A}$.
