The current can be calculated using the formula $I = \frac{q}{t}$, where $q$ is the charge and $t$ is the time. Given $4.0 \times 10^{16}$ electrons, each with a charge of $1.60 \times 10^{-19} C$, the total charge $q = 4.0 \times 10^{16} \times 1.60 \times 10^{-19} C = 6.4 \times 10^{-3} C$. With $t = 0.50 s$, the current $I = \frac{6.4 \times 10^{-3} C}{0.50 s} = 0.0128 A$, which rounds to $0.013 A$.
