Charge against time for different currents

Three currents flow for a minute: $0.2\ \text{A}$, $0.5\ \text{A}$ and $1.2\ \text{A}$. You will make the program find the charge each one moves in $60\ \text{s}$, the time the middle current needs to move $25\ \text{C}$, and the number of electrons the largest current moves in a minute. Then it draws charge against time.

The idea. $Q = It$, and one electron carries $1.6 \times 10^{-19}\ \text{C}$.

Your tasks.

1. Inside the loop, work out Q, the charge moved in $60\ \text{s}$ by the current I.
2. Find t25, the time for $0.5\ \text{A}$ to move $25\ \text{C}$, in seconds.
3. Find n, the number of electrons that $1.2\ \text{A}$ moves in $60\ \text{s}$.
