Question
Do you know the charge of an electron in coulomb? How many electrons are there in one coulomb of charge?
Solution
We know that,
Charge on an electron, e = 1.6 x 10–19 C
Using the formula,
q=ne
n = q/e
q = 1C and e= 1.6 x 10–19 C
Therefore, One coulomb is equivalent to the charge carried by 6.25 x 1018 electrons.
