If 1.34 ✕ 1020 electrons move through a pocket calculator during a full day's operation, how many coulombs of charge moved through it?

Given :

Number of operations move through a pocket calculator during a full day's operation , .

To Find :

How many coulombs of charge moved through it .

Solution :

We know , charge in  one electron is :

So , charge on n electron is :

Therefore , -21.44 coulombs of charge is moved through it .

Hence , this is the required solution .

what is the question because that is not a question.

where are the vectors ?
