Electricity question

Answer 1

i used the formula t = Q/I
t = 3.204 x 10^-19 / .1
t = 3.204 x 10^-18
which is the time for 1 electron, therefore
3.204 x 10^-18s = 1e
1s = 3.121 x 10^17
correct??

Answer 2

so like 3 x 10^17 electrons per second?

Answer 3

current= Q/t
current=0.1A, t=1s
Q=0.1C
where \(1e=1.6x 10^{-19} C\)
so, no.of electrons =\(\frac{0.1}{1.6x 10^{-19}}\)

Answer 4

\[I=0.10[\text A]\\=0.10\tfrac{[\text C]}{[\text s]}\\=0.10\tfrac{[\text C]}{[\text s]}\div1\\=0.10\frac{[\text C]}{[\text s]}\div\frac{1.6\times10^{-19}[\text C]}{[\text {electron}]}\\=0.10\div1.6\times10^{-19}\frac{[\text {electron}]}{[\text s]}\\=6.24\times10^{17}\frac{[\text {electron}]}{[\text s]}\]
