How many electrons is 2415 Coulombs?

Question

anonymous · Answer

oh...First you should understand that coulombs is related to Current*time: q=I*t
So you ought to consider the time(s)^-^

No, that's wrong.  

Coulomb is a measure of charge and there is no need to relate it to current.  (Instead, we define current in terms of charge.)

The charge on an electron is
$$ e = 1.602 \times 10^{-19} $$

Hence the number of electrons required for a charge of 2415 C is
$$ \frac{2415}{e} = \frac{2415}{1.602 \times 10^{-19} = ... $$

Coulomb is a measure of charge and there is no need to relate it to current.  (Instead, we define current in terms of charge.)

The charge on an electron is
$$ e=1.602 \times 10^{−19} $$ 

Hence the number of electrons required for a charge of 2415 C is

$$ \frac{2415}{e} = \frac{2415}{1.602 \times 10^{-19}}  = ... $$
