Elektricitet

En ström på 0,1A går genom en kabel. Hur många elektroner passerar varje sekund?

From the basic idea , we know, Q=I * t. where Q being the charge , I the amount of current flowing and t, the duration of time for which he current is flowing.

Putting the values we get, 2 * (10 * 60)= 1200 coulombs. (SI unit of time being sec).

Now the number of electrons flowing can be calculated as, 1200/e where e is the electronic charge, ( e= 1.6 * 10^(-19) ) which comes out approximately 7.5 * 10^(21)

Var kom faktorn 2 ifrån (och 60 för den delen)?
